"\xE1"ISO-8859-1"\xC3\xA1"UTF-8C Here is my simple SimpleXML wrapper function. Section and property names are case insensitive.[9]. exif_read_data() reads the EXIF headers from an image file. These days, with so many people browsing the web via iPads, you have to explicitly check to see if the input isset($_FILES['profile_pic']) before calling into it, else you'll get the aforementioned error message. ' To determine whether upload was successful you should check for error being UPLOAD_ERR_OK instead of checking the file size. may be raised for unsupported tags or other potential error conditions, but the UNIX macOS \n, PHP For example, both themes contain the same templatecategory.php, then child themes template is used.If a child theme contains the specific template such ascategory-unicorns.phpand the parent theme contains lower prioritized template such ascategory.php, then child themescategory-unicorns.phpis used.Contrary, if a child theme contains general template only such ascategory.phpand the parent theme contains the specific one such ascategory-unicorns.php, then parents templatecategory-unicorns.phpis used. It doesn't seem to be documented anywhere, but you can refer to an element "value" for the purpose of changing it like so: Theres a problem with the below workaround when serializing fields containing html CDATA. __set(), __isset() As the INI file format is not rigidly defined, many parsers support features beyond the basics already described. in IFD0 section. object string, Resource "Resource id #1" For example: " and suggesting the following:

PHP 256 Unicode , : form There is no need to do 8u351 LTS (October18, 2022; 54 days ago(2022-10-18)[32]) []. The following example file has two sections: one for the owner of the software, and one for a payroll database connection. This tutorial will walk through the various ways to read files in PHP - Into a string, an array, line-by-line, and more. Use ftell() to find the current position of the pointer and rewind() to rewind the pointer position. It then looks up the requested INI setting in that part of the Registry. Format accepted by DateTimeInterface::format().. timestamp. Zend Multibyte - Some software supports the use of the number sign (#) as an alternative to the semicolon for indicating comments, especially under Unix, where it mirrors shell comments. Obviously don't use these for comparison in real code. string While the template hierarchy is easier to understand as a diagram, the following sections describe the order in which template files are called by WordPress for a number of query types. The special value none disables auto-prepending. UTF-8 . In addition, platform-agnostic software may use this file format for configuration. If you are looking for the $_FILES['error'] code explanations, be sure to read: The format of this array is (assuming your form has two input type=file fields named "file1", "file2", etc): Comprehensive iterator for direct "flat" access for any-level arrayed , in any combination: // Here's how to generate an automated name that incorporates the "node path", e.g. Some parsers allow section nesting, using dots as path delimiters: In some cases relative nesting is supported too, where a leading dot expresses nesting to the previous section:[8]. [1] The name of these configuration files comes from the filename extension INI, for initialization, used in the MS-DOS operating system which popularized this method of software configuration. If you're uploading multiple files and you name your file inputs "upload[]" the $_FILES array will look different than the var_dump posted below. In this case, the @ prefix on the default prevents any reads from going to the dbsettings.ini file on disk. The "database" Registry entry does not have the @ prefix on the value; thus, for the [database] section only, settings in the Registry are taken first followed by settings in the dbsettings.ini file on disk. In the following example, we construct an ostringstream object where we insert the rdbuf functions return value. . Here's a function that I have used to get a nice simple array of all incoming files from a page. found in the XML data. THUMBNAIL, and COMMENT Overloading in PHP provides means to dynamically The SMTP implementation (Windows only) of mail() differs in many ways from the sendmail implementation. This probably saved me a ton of time. Overloading The name appears to the left of the equals sign. : IntelliSense) for the affected classes. The arguments are evaluated from left to right, before the function is actually called (eager evaluation).PHP supports passing arguments by value (the default), passing by reference, and default argument values. PHP_MANDIR (string) Specifies where the manpages were installed into. 1 PHP When nothing is chosen to be uploaded, the key in $_FILES will still be there, but it should have error equal UPLOAD_ERR_NO_FILE. , PHP 7.3.0 //How can implement __call function you understand better. The __set() Leading and trailing whitespaces around the outside of the property name are ignored. I recommend using finfo_open (. The rest of this section will use the terms So, in this case the profile call for the [owner] section is mapped through to: where the "name" Registry entry name is found to match the requested INI key. property being interacted with. # Modified Version of cameraUsed, no longer returns date. As was said before don't use var_dump() or print_r() to see SimpleXML object structure as they do not returns always what you expect. itself. because of the way PHP processes the assignment operator. Just like this: Others have posted about how the $_FILES array organizes data differently depending on whether the HTML input is a single or multiple type, so it seems to be a common enough problem. simplexml_load_string() will return an object of Similarly, __get() is never called when - , PHP within the lifetime of a script being executed (ie a Web request or CLI Human Language and Character Encoding Support. Optional "global" properties may also be allowed, that are declared before any section is declared. Later XML-based configuration files became a popular choice for encoding configuration in text files. // $image now contains a resource with the image oriented correctly. Because it REALLY is a bad name. __set() is run when writing data to None of the arguments of these magic methods can be This was the case regardless of whether or not the end user actually uploaded a file. with other sections. Doing this: Since this was getting me for a little bit, I figure I better pipe in here for anyone who's thinking about traversing some variable tree. POST method uploads If WordPress cannot find a template file with a matching name, it will skip to the next file in the hierarchy. This way you can read meta data session_start() creates a session or resumes the current one based on a session identifier passed via a GET or POST request, or passed via a cookie. Git configuration files are similar to INI files. extension will not attempt to figure out the encoding on its own, and it is up to the user , heredoc The number sign might be included in the key name in other dialects and ignored as such. But instead of a flat string, file() will read into an array instead, with each element being a different line.

If the argument supplied for this parameter is NULL, the default is an empty string, "". ], string Note that you should read "Variables/Variable scope" if you are looking for static keyword use for declaring static variables inside functions (or methods). or non-existing properties. E_WARNING EXIF headers tend to be present in JPEG/TIFF images generated by digital cameras, but unfortunately each digital camera maker has a different idea of how to actually tag their images, so you can't always rely on a specific Exif header being present. Copyright.Photographer and This allows for explicit declaration of whitespace, and/or for quoting of special characters (equals, semicolon, etc.). UserComment. Here is a list of all available filters in the template hierarchy: For example, lets take the default author hierarchy: To add author-{role}.php before author.php, we can manipulate the actual hierarchy using the author_template template type. Starting with Windows 95, Microsoft began strongly promoting the use of Windows registry over the INI file. Without the requirements above, the file upload will not work. tag. Semicolons (;) at the beginning of the line indicate a comment. (For rendering a single post type template, refer to the single post display section above.). If you want a parsed variable surrounded by curly braces, just double the curly braces: You may use heredoc syntax to comment out large blocks of code, as follows: // end-of-line comment will be masked so will regular PHP: I though that it would be helpful to add this comment so that the information at least appears on the right page on the PHP site. If WordPress cannot find a template file with a matching name, it will skip to the next file in the hierarchy. This decision however has not been immune to critiques, due to the fact that the registry is monolithic, opaque and binary, must be in sync with the filesystem, and represents a single point of failure for the operating system.[47].

I use dynamically generated images that require a little touch-up before being displayed. The $name argument is the name of the Height and Width are computed the PHP required_sections COMPUTED, Here is my update to Bob's simple SimpleXML wrapper function. I had a hard time finding this documented, so posting it here in case it helps someone: A simpler way to transform the result into an array (requires json module). exif.decode_unicode_motorola and . "Array"echo Just to reinforce and elaborate on what DevilDude at darkmaker dot com said way down there on 22-Sep-2004 07:57. paths : It is a string, or list of strings, for input path(s). Obviously this will open up an array of implementations where at one point it was just not possible. the header names and the array values are the values associated with Having url rewrite patterns in .htaccess file which modify your urls can affect $_FILES sometimes. A simple extension that adds a method for retrieving a specific attribute: Please note that not all LIBXML options are supported with the options argument. If a tag contains CDATA, SimpleXML remembers that fact, by representing it separately from the string content of the element. Some programs use duplicate property names to implement multi-valued properties. WritePrivateProfileInt() does not exist. This handles the single case, the multiple file case, and even submitting multiple file arrays. Thus posting this. instead, looking for people to make the resources locale, you MUST provide approprate documentation for everybody. static. arguments. Errors of level E_WARNING and/or E_NOTICE PHP 7.3.0 , $a = $obj->b = 8; PHP will not call an overloaded method from within the same overloaded method. Summary: in this tutorial, youll learn how to use the PHP explode() function to split a string by a separator into an array of strings.. Introduction to the PHP explode() function. [citation needed] XML allows arbitrarily complex levels and nesting, and has standard mechanisms for encoding binary data. the specified class. to properly specify the encoding for which to use for decoding by setting one of these two The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in baseTimestamp, or the current time if baseTimestamp is not supplied. // Let's see our BadPractice in a production environment! It returns an array with the parameters. /* prints complete structure of each folder element: Be careful checking for parse errors. reference. Beware that consistent with "String conversion to numbers": '(intstr == int) incorrectly tests as true.'. heredoc nowdoc There seems to be a lot of talk about SimpleXML having a "problem" with CDATA, and writing functions to rip it out, etc. The String Cheese Incident (SCI) is an American jam band from Crested Butte and Telluride, Colorado, formed in 1993.The band is composed of Michael Kang (acoustic/electric mandolin, electric guitar, and violin), Michael Travis (drums and percussion), Bill Nershi (acoustic guitar, lap steel guitar, and electric slide guitar), Kyle Hollingsworth (piano, organ, Rhodes, and [2], The primary mechanism of software configuration in Windows was originally a text file format that comprised text lines with one keyvalue pair per line, organized into sections. First, download a webpage https://www.php.net using the file_get_contents() function. , Heredoc string heredoc In the Windows implementation the equal sign and the semicolon are reserved characters and cannot appear in the key. Ifhome.phpdoes not exist, WordPress will useindex.php. After using array_push you may wish to read the top (last) array element one or more times before using array_pop. Php 5 has a simple recursion system that stops you from using overloading within an overloading function, this means you cannot get an overloaded variable within the __get method, or within any functions/methods called by the _get method, you can however call __get manualy within itself to do the same thing. , For instance, the following line may be interpreted as a comment in one dialect, but create a variable named "#var" in another dialect. "" bool Here's a useful class for logging function calls. and such. and __callStatic() methods, /**Overloadingnotusedondeclaredproperties. Explicitlyspecifytheendofthevariablenamebyenclosingitinbraces: "Changingthecharacteratindex-3toogives, //$foo[bar]. Some implementations offer varying support for an escape character, typically with the backslash (\) following the C syntax. same way getimagesize() does so their values must not be Instead, I hacked up a regex that worked fairly well as a replacement, '@\x12\x01\x03\x00\x01\x00\x00\x00(.)\x00\x00\x00@'. PHP 7.4.0 PHP 8.0.0 , The front page template takes precedence over the blog postsindex (home.php) template. auto_prepend_file string. (stream wrappers are also supported as usual) The exif Here is an easy hack to allow double-quoted strings and heredocs to contain arbitrary expressions in curly braces syntax, including constants and other function calls: //Parse error: syntax error, unexpected '}', expecting '['. The COMPUTED section will store both in The privacy-policy.php template file is used to render your sites Privacy Policy page. "" A nice trick to reorder the $_FILES array when you use a input name as array is: A note of security: Don't ever trust $_FILES["image"]["type"]. Historically, ways for expressing nesting alternative to the dot have existed too (for example, IBM's driver file for Microsoft Windows devlist.ini, in which the backslash was used as nesting delimiter in the form of [A\B\C]; or Microsoft Visual Studio's AEMANAGR.INI file, which used a completely different syntax in the form of [A] and B,C,P = V). Unlike other codes here, this working well on any depth of $_FILES. for example : Using magic methods, especially __get(), __set(), and __call() will effectively disable autocomplete in most IDEs (eg. If you are not focused enough, then don't use it. See. argument is an enumerated array containing the parameters automatic global, variable. print XSS can cause a variety of problems for the end user that range in severity from an annoyance to complete account compromise. { } PHP 7.1.0 The getimagesize() function will determine the size of any supported given image file and return the dimensions along with the file type and a height/width text string to be used inside a normal HTML IMG tag and the correspondent HTTP content type.. getimagesize() can also return some more information in image_info parameter. schema : It is an optional These will either be a built-in save handler provided by default or by PHP extensions (such as SQLite or array Coding Horror, "Comment on ".INI compatibility is a worthy goal" issue on GitHub", Cloanto Implementation of INI File Format, https://en.wikipedia.org/w/index.php?title=INI_file&oldid=1116101864, Articles with unsourced statements from January 2014, Creative Commons Attribution-ShareAlike License 3.0, Discontinued last version is 5.0.5, from November 2009, This page was last edited on 14 October 2022, at 20:27. print_r() var_dump() , PHP string While PHP does not support true overloading natively, I have to disagree with those that state this can't be achieved trough __call. The basic element contained in an INI file is the key or property. string, PHP 7.1.0 PHP_BINDIR (string) The value --bindir was set to at configure. This function may evaluates to false. Always use `=== FALSE` when checking for parse errors. part of any header returned. # Return either an empty array, or the details which we were able to extrapolate. I couldn't find any anywhere, so I made some. Support for the following EXIF formats were added. Unicode , //Thiswillnotexpand:\nanewline, Exampleofstringspanningmultiplelines. But I wanted to answer the performance question once and for all, using sufficient numbers of iterations and a modern PHP version. It took some research : The example provided for displaying exif array content is not working in recent version because not all entry values are of array type. All subsequent versions of Windows have used the Windows Registry for system configuration, but applications built on the .NET Framework use special XML .config files. square brackets for sections, newlines for delimiting different nodes, etc.). Here is a possible gotcha related to oddness involved with accessing strings by character past the end of the string: Leading zeroes in strings are (least-surprise) not treated as octal. The format has become an informal standard in many contexts of configuration, but many applications on other operating systems use different file name extensions, such as conf and cfg. This handles the single case, the multiple file case, and even submitting multiple file arrays. PHP 7.3.0 , NULL , PHP (that's really dynamic! 32 string 2GB 2147483647 , \\\ This can either be a path to the file If so the IFD section only contains the encoding Be extra careful when using __call(): if you typo a function call somewhere it won't trigger an undefined function error, but get passed to __call() instead, possibly causing all sorts of bizarre side effects. Nontypicall array comes in php after the submission.I wrote a small function to restate it to the familiar look. $str[42] string Don't forget about new E_WARNING and E_NOTICE errors from PHP 7.1.x: they have been introduced when invalid strings are coerced using operators expecting numbers (+ - * / ** % << >> | & ^) or their assignment equivalents. PHP is a server scripting language, and a powerful tool for making dynamic and interactive Web pages. This function works on many file inputs on the page and also if the inputs are ''. PHP ; PHP 8.1.x PHP 8.2.x; PHP 8.0.x PHP 8.1.x This way no matter what, before ever touching the files array I call this regardless of what it might be: //make there there is a file, and see if the first item is also an array, //array file submit, eg name="model[file]", // multi-array file submit, eg name="model[file][]". // But this prints "There's stuff here", proving that. traditionally provides the ability to have multiple methods I've written this function to restructure deeply nested $_FILES arrays, so that the parameters for each file are grouped together. The result is that any settings not found in the Registry are not looked for in the INI file. , Implementation of various "special characters" with escape sequences is also seen. If for some reason you need to mix-and-match the types, or you're not sure which how many files you'll be expecting from a multiple input, this is a very useful way to reorganize the $_FILES array. Among them, TOML most closely resembles INI, but the idea to make TOML deliberately compatible with a large subset of INI was rejected. Note that unlike other post-types, page is special to WordPress and uses the following path: Rendering category archive index pages uses the following path in WordPress: To display a tag archive index page, WordPress uses the following path: Custom taxonomies use a slightly different template file path: Custom Post Types use the following path to render the appropriate archive index page. Initialization file mapping creates a mapping between an INI file and the Registry. The require statement is also used to include a file into the PHP code. The standard Windows function GetPrivateProfileString supports this, and will remove quotation marks that surround the values. UTF-8 ISO-8859-1, PHP __get() will return null ISO-8859-1 ISO-8859-1 Zend Multibyte This way no matter what, before ever touching the files array I call this regardless of what it might be: getName(): //ThisisthereturnvalueofgetName():{getName()}, "ThisisthereturnvalueofgetName():{getName()}", PHP 7.1.0 string string { $ format : It is an optional string for format of the data source. It can store two values. Rasmus Lerdorf, Kevin Tatroe, Peter MacIntyre. string echo print with the same name but different quantities and types of Best way to check if $_FILES is empty or not is to check if the name of the index 0 is set. /* bool/array unserialize_xml ( string $input [ , callback $callback ] ). This is because iOS devices running Safari disable file inputs thereby causing them to be treated as if they don't exist. mysql_real_escape_string() calls MySQL's library function mysql_real_escape_string, which prepends backslashes to the following characters: \x00, \n, An empty SimpleXMLElement may resolve to FALSE, and if your XML contains no text or only contains namespaced elements your error check may be wrong. The COMPUTED will also contain the entry The format was maintained in 16-bit Microsoft Windows platforms up through Windows 3.1x. PHP 7.1.0 fatal As you can see, there are a lot of rules to what path WordPress takes. I've been a PHP programmer for a decade, and I've always been using the "single-quoted literal" and "period-concatenation" method of string creation. There are many methods to convert string into number in PHP some of them are discussed below: Method 1: Using number_format() Function. A file is supposed to contain a thumbnail if it has a second. You can use the complex syntax to put the value of both object properties AND object methods inside a string. The WordPress template system lets you filter the hierarchy. Function arguments. It is human-readable and simple to parse, so it is a usable format for configuration files that do not require much greater complexity. global $variable; to access it within functions or methods. Some valid files with special filenames could break this; for example, a file named "used.to.be.a.png.file.gif" would cause this script to attempt to load the file as a PNG. Is a comma separated list of sections that need to be present in file Please note that when resizing images with GD and most image processing scripts or applications you will loose the EXIF information. The following shows the syntax of the explode() function: It would be nice if PHP let me read that file BEFORE I tried to move_uploaded_file on it, but PHP won't, presumably under the assumption that I'd be doing something dangerous to read an untrusted file. 17.0.5 LTS (October18, 2022; 54 days ago(2022-10-18)) [] The $name argument is the name of the always become arrays as they may contain values whose names conflict The attached "new FILES_flattened" class flattens the $_FILES array, for any combination of "single" files, multi-file arrays with given indices [i] or multi-file array with [] indices, even multi-level multi-file arrays [i][j][n]. method's $value argument specifies the In most use cases, it wont be required since PHP does implicit type conversion. 0NUL bytes Hash, (string) strval() simple_load_string did not recognize short one. Interprets a string of XML into an object. tagged data is read. Here is my version of $_FILES rearrange. Problem with "Some Text" on value(s), exif[IFD0][Title] for example, when they were edited trough windows right click properties and then got read with the read_exif_data() function. operator for testing the return value of this If the category slug is unicorns, then WordPress looks for a template file named, Finally, WordPress ultimately falls back to its own. This can be used to script common sequences of operations, or to make "pluggable" operation sequences in header files that can be replayed on objects later. entries. , They are often already included in frameworks and toolkits. If your blog is at http://example.com/blog/ and a visitor clicks on a link to a category page such ashttp://example.com/blog/category/your-cat/, WordPress looks for a template file in the current themes directory that matches the categorys ID to generate the correct page. If mbstring is enabled, exif will attempt to process Code language: HTML, XML (xml) How it works. '+', methods to refer to this combination of declaration inaccessible properties and inaccessible __unset() is invoked when ({}) , string 0 section. Other things to notice: The type="file" attribute of the tag shows the input field as a file-select control, with a "Browse" button next to the input control ; The form above sends data to a file called "upload.php", which we will create next. null, PHP 7.4 {} The structure of this array is outlined in the process) and won't be reused. A URL can be used as a filename with this function if the fopen wrappers have been enabled. to the EXIF specification (http://exif.org/Exif2-2.PDF, page 20). The first call fails because the image has no header information. and __unset() methods. Example #2 //Invalid. Whitespace is occasionally used in the Linux world.[8]. one can establish in a class for various action types. simplexml_load_string Default to parquet. <<< Under Unix, many different configuration libraries exist to access INI files. The Privacy Policy page template takes precedence over the static page (page.php) template. string E_WARNING, : or a byte array. We have 30 file inputs on one page for upload to server. Otherwise, only the I realize there are a number of posts here for reformating the php $_FILES array, but they don't handle all cases. This leaves, for now, only unconditionally declared functions in the global namespace, private class methods, and code new to Core, as candidates for adding type declarations. information. If neither of those files exist, it will use the index.php file. These three alternative formats can nest arbitrarily, but have a different syntax than the INI file. The front-page.php template file is used to render your sites front page, whether the front page displays the blog posts index (mentioned above) or a static page. inaccessible methods in an object context. //Valid. Otherwise, PHP treats the element as an object." Note that the file pointer position is not changed after this function returns. Notes. You can do "bad practice" with right code too. [46] INI files are typically limited to two levels (sections and properties) and do not handle binary data well. In some implementations, duplicate sections simply merge their properties, as if they occurred contiguously. An INI file is a configuration file for computer software that consists of a text-based content with a structure and syntax comprising keyvalue pairs for properties, and sections that organize the properties. Be careful of __call in case you have a protected/private method. Some implementations allow values to be quoted, typically using double quotes and/or apostrophes. This function is similar to file(), except that file_get_contents() returns the file in a string, starting at the specified offset up to length bytes. Examples of INI parsers for Unix include GLib, iniparser and libconfini. all scopes throughout a script. inaccessible methods in a static context. You may use this optional parameter so that For any other content type then HTML try to modfiy function parseCDATA. As mentioned , you should check the error index of the upload. //Openathefile,thisshouldbeinbinarymode, 'Error:Unabletoopenimageforreading'. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide. PHP 8.0.0 , string $str{42} It may seem obvious, but remember, when deciding whether to use __get, __set, and __call as a way to access the data in your class (as opposed to hard-coding getters and setters), keep in mind that this will prevent any sort of autocomplete, highlighting, or documentation that your ide mite do. Please reference the following bug reports: Photos processed in Picasa often contain garbage data in the "MAKERNOTE" section and under EXIF.MakerNote, (UTF8) like: Human Language and Character Encoding Support, http://php.net/manual/en/function.imagerotate.php, http://php.net/manual/en/function.imagecopy.php#42803, http://php.net/manual/en/function.exif-read-data.php, http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/EXIF.html, FileName, FileSize, FileDateTime, SectionsFound, html, Width, Height, IsColor, and more if available. The function itself form"\x61\xCC\x81"UTF-8D Some parsers did not offer nesting support at all and were hierarchy-blind, but nesting could still be partially emulated by exploiting the fact that [A.B.C] constitutes a unique identifier. By default, WordPress sets your sites home page to display your latest blog posts. [49], text/plain, application/textedit, zz-application/zz-winassoc-ini, ; use IP address in case network name resolution is not working, // N.B. PHP is a widely-used, free, and efficient alternative to competitors such as Microsoft's ASP. It basically just flattens the $FILES array. The second occurrence of a property name may cause an abort, it may be ignored (and the value discarded), or it may override the first occurrence (with the first value discarded). In normal imagefiles this contains If the file is used to pass a stream to this function, then the stream Any single expression, however complex, that starts with $ (i.e., a variable) can be {}-embedded in a double-quoted string: Human Language and Character Encoding Support, https://www.php.net/manual/en/migration71.other-changes.php, which silently overflows to fit in a byte exif_read_data() reads the THis is an solution to convert Cyrillic and umlaut characters as file name when uplaoding files into needed encoding.

Hope helps someone to not waste time as i did :-P. if you want to use a class which exists in a name space, use it full name. From - darkain at darkain dot com 's example. Specifies the name of a file that is automatically parsed before the main file. If WordPress cannot find any matching template file, the themes index.php file will be used.. The overloading methods are invoked when interacting with up chaining assignments together like this: A warning is issued if one of the magic overloading // Now you can use any SOAP method without needing a wrapper. category LC_NUMERIC setlocale(), array Skip to content. __get() is utilized for reading data from inaccessible (protected or private) or non-existing properties. When session_start() is called or when a session auto starts, PHP will call the open and read session save handlers. serialize() , PHP string 'Calls __isset() on demo as expected when executing isset( $x->a )', 'Calls __get() on demo without call to __isset() when executing isset( $x->a->b )'. While the exact structure of this string should not be relied on I think this page should have a "See also" link to static function variables. Interprets a string of XML into an object. To determine which template file to use, WordPress: With the exception of the basic index.php template file, you can choose whether you want to implement a particular template file or not. To read the top array element efficiently, use the 'current' function. function. In block themes, HTML files are used instead, but the template hierarchy is the same.
