pathinfo — Zwraca informacje o ścieżce do pliku
Opis
mixed pathinfo
( string
$ścieżka
[, int $opcje = PATHINFO_DIRNAME | PATHINFO_BASENAME | PATHINFO_EXTENSION | PATHINFO_FILENAME
] )
pathinfo() zwraca asocjacyjną tablicę
zawierającą informacje o ścieżce.
Parametry
-
ścieżka -
Ścieżka która jest sprawdzana
-
opcje -
Możesz określić, który element zostanie zwrócony, za pomocą opcjonalnego parametru
opcje. Składajego się zPATHINFO_DIRNAME,PATHINFO_BASENAME,PATHINFO_EXTENSIONiPATHINFO_FILENAME. Domyślnie zwracane są wszystkie elementy.
Zwracane wartości
Zwracane są następujące elementy asocjacyjnej tablicy array: dirname, basename, extension (jeśli wystąpi) i filename.
Jeśli parametr opcje zostanie użyty, funkcja zwróci
string w przypadku gdy nie zarządano wszystkich elementów.

pathinfo will return null if 0 or null is specified for the option argument.
So you'll need to define it's value manually if the option field is omitted, to provide the default functionality.
<?php
public function getFileInfo($source = null, $option = null){
if(!$option){
//1 + 2 + 4
$option = PATHINFO_DIRNAME + PATHINFO_BASENAME + PATHINFO_EXTENSION;
if(defined('PATHINFO_FILENAME'))
$option += PATHINFO_FILENAME; //8
}
return pathinfo($source, $option);
}
$obj->getFileInfo("/test/file/someFile.txt");

Sometimes we want to get an array of each component in the pathname associated with the correspondent path to that directory. We need it for creating breadCrumbs and stuff like that. So here it goes:
<?php
/* Function parsePathComponents
* parse through all path components
* resolves the cross platform slash issue
* eliminates extra redundant slashes
* @return associative array: ComponentName=>CorrespondentPath
*/
/* Array */ function parsePathComponents($path,$endSlash=true,$base=false)
{
for(
$path = trim($path),
$slash = strstr(PHP_OS,'WIN') ? '\/' : '/',
$retArray = array(),
$str = $temp = "",
$x = 0;
$char = @$path{$x}; $x++)
{
if(!strstr($slash,$char)) $temp .= $char;
elseif($temp){
$str .= $temp;
$retArray[$temp] = $str.($endSlash ? $slash{0} : '');
$str .= $slash{0};
$temp = "";
}
}
$base&&$temp and $retArray[$temp] = $str.$temp;
return $retArray;
}
// Testing in WINDOWS
// NOTE: UNIX will return paths with normal slashes
// return array with path names ending with a slash
$path = '/my//stupid//path/to///some/file.php';
$pathComps = parsePathComponents($path);
print_r($pathComps);
//Array ( [my] => my\ [stupid] => my\stupid\ [path] => my\stupid\path\ [to] => my\stupid\path\to\ [some] => my\stupid\path\to\some\ )
$path = 'my/other//path/';
// return paths not ending with slash
print_r(parsePathComponents($path,false));
// Array ( [my] => my [other] => my\other [path] => my\other\path )
$path = 'my//other/path/to///file.php';
// use third argument = true: for capturing the "file.php" base
print_r(parsePathComponents($path,true,true));
//Array ( [my] => my\ [other] => my\other\ [path] => my\other\path\ [to] => my\other\path\to\ [file.php] => my\other\path\to\file.php )

Here is a simple function that gets the extension of a file. Simply using PATHINFO_EXTENSION will yield incorrect results if the path contains a query string with dots in the parameter names (for eg. &x.1=2&y.1=5), so this function eliminates the query string first and subsequently runs PATHINFO_EXTENSION on the clean path/url.
<?php
function extension($path) {
$qpos = strpos($path, "?");
if ($qpos!==false) $path = substr($path, 0, $qpos);
$extension = pathinfo($path, PATHINFO_EXTENSION);
return $extension;
}
?>

For a good example of how platform independent this function is have a look at the different return values that Lostindream and I experienced. Mine is above and Lostindream's is below:
Array
(
[dirname] => /www/psychicblast/images/1
[basename] => my three girlfriends.jpg
[extension] => jpg
)
Array
(
[dirname] => /www/htdocs
[basename] => index.html
[extension] => html
[filename] => index
)

A warning: this function varies depending on the platform it is being run on. For example, pathinfo('C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe') will return a different result when run through a winOS PHP platform (local development) vs. a server's UNIX-based OS. A bit like the Locale settings, but unexpected.

at example from "qutechie at gmail dot com" you can only replace function 'strpos' with 'strrpos'. (strrpos — Find position of last occurrence of a char in a string)
It's simple. For example:
<?php
function filePath($filePath)
{
$fileParts = pathinfo($filePath);
if(!isset($fileParts['filename']))
{$fileParts['filename'] = substr($fileParts['basename'], 0, strrpos($fileParts['basename'], '.'));}
return $fileParts;
}
$filePath = filePath('/www/htdocs/index.html');
print_r($filePath);
?>
Output will be:
Array
(
[dirname] => /www/htdocs
[basename] => index.html
[extension] => html
[filename] => index
)

qutechie at gmail dot com wrote a fix for support for filename in PHP 4; however it gets it wrong whenever you have a filename with a . in it (so foo.bar.jpg would return foo instead of foo.bar).
A fix would be:
<?php
if(!isset($path_parts['filename'])){
$reversed_filename = strrev( $path_parts['basename'] );
$path_parts['filename'] = strrev( substr( $reversed_filename, strpos( $reversed_filename, '.' ) + 1 ) );
}
?>
The idea is that you reverse the string and create a substring that starts after the first '.' and then reverse the result.

Quick fix for lack of support for 'filename' in php4
<?php
$path_parts = pathinfo('/www/htdocs/index.html');
echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
echo $path_parts['filename'], "\n"; // since PHP 5.2.0
// if php4
if(!isset($path_parts['filename'])){
$path_parts['filename'] = substr($path_parts['basename'], 0,strpos($path_parts['basename'],'.'));
}

if you call pathinfo with a filename in url-style (example.php?with=parameter), make sure you remove the given parameters before, otherwise they will be returned as part of the extension.
extension => php?with=parameter

Note that this function seems to just perform string operations, and will work even on a non-existent path, e.g.
<?php
print_r(pathinfo('/no/where/file.txt'));
?>
which will output:
Array
(
[dirname] => /no/where
[basename] => file.txt
[extension] => txt
[filename] => file
)

Building on David Blinco's function, the following will:
1. Return the correct protocol for secure requests (https)
2. Throw an exception for invalid files
3. Ensure the returned url separates directories with forward slashes (David's will not on Windows systems).
function mapPath ($filepath) {
$realpath = realpath($filepath);
$dir;
// Verify that the path passed is real and harvest the bottom directory
if (is_file($realpath)) {
$dir = dirname($realpath);
}
elseif (is_dir($realpath)) {
$dir = $realpath;
}
else {
throw new Exception('File does not exist: ' . $realpath);
}
// Make sure the path is not lower than the server root
if (strlen($dir) < strlen($_SERVER['DOCUMENT_ROOT']))
throw new Exception("Cannot create http path below server http root.");
$path = ((isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) != 'off') ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . substr($realpath, strlen($_SERVER['DOCUMENT_ROOT']));
if (DIRECTORY_SEPARATOR == '\\')
$path = str_replace('\\', '/', $path);
return $path;
}

This function is not perfect, but you can use it to convert a relative path to a URL.
Please email me if you can make any improvements.
<?php
function mapURL($relPath) {
$filePathName = realpath($relPath);
$filePath = realpath(dirname($relPath));
$basePath = realpath($_SERVER['DOCUMENT_ROOT']);
// can not create URL for directory lower than DOCUMENT_ROOT
if (strlen($basePath) > strlen($filePath)) {
return '';
}
return 'http://' . $_SERVER['HTTP_HOST'] . substr($filePathName, strlen($basePath));
}

If you have filename with utf-8 characters, pathinfo will strip them away:
print_r(pathinfo("/mnt/files/飛兒樂團光茫.mp3"));
.. will display:
Array
(
[dirname] => /mnt/files
[basename] => .mp3
[extension] => mp3
[filename] =>
)
mrnemesis at ntlworld dot com

Note that in PHP 4 (if you're stuck using it), pathinfo only provides dirname, basename, and extension, but not filename. This function will not split a file's stem and extension for you.

Heres a funciton to get the same results from php 4+ but you will have to call pathinfo_filename() instead of pathinfo().
<?php
if(version_compare(phpversion(), "5.2.0", "<")) {
function pathinfo_filename($path) {
$temp = pathinfo($path);
if($temp['extension'])
$temp['filename'] = substr($temp['basename'],0 ,strlen($temp['basename'])-strlen($temp['extension'])-1);
return $temp;
}
} else {
function pathinfo_filename($path) {
return pathinfo($path);
}
}
?>

You shouldn't assign values as it is described in previous post
// wrong:
list( $dirname, $basename, $extension, $filename ) = array_values( pathinfo($file) );
if $file has no extension, you get wrong variable values: $extension would be assigned with 'filename' array element of pathinfo() result, but $filename - would be empty.
phpnet at whoisgregg dot com
30-May-2007 11:01
If you want to easily assign the values returned by pathinfo to separate variable names, list isn't enough. You can use array_values() first to convert the associative array into the indexed array that list() expects:
// throws notices, variables aren't set
list( $dirname, $basename, $extension, $filename ) = pathinfo($file);
// works
list( $dirname, $basename, $extension, $filename ) = array_values( pathinfo($file) );

Sometimes, it's interessant to get the basename without extension.
So, I appended a new entry 'basenameWE' (Basename Without Extension) to the returned array.
<?php
// pathinfo improved
function pathinfo_im($path) {
$tab = pathinfo($path);
$tab["basenameWE"] = substr($tab["basename"],0
,strlen($tab["basename"]) - (strlen($tab["extension"]) + 1) );
return $tab;
}
$my_path = "/var/www/html/example.html";
echo "<pre>\n";
print_r( pathinfo_im($my_path) );
echo "</pre>\n";
?>
Out :
Array
(
[dirname] => /var/www/html
[basename] => example.html
[extension] => html
[basenameWE] => example
)

It is true that if you put a directory into pathinfo, usually the extension is empty. But, if the directory name is /www/example.com/ for example, you will have the following output:
Array
(
[dirname] => /www
[basename] => example.com
[extension] => com
)
So, it is the same as a file.

If a file has more than one 'file extension' (seperated by periods), the last one will be returned.
For example:
<?php
$pathinfo = pathinfo('/dir/test.tar.gz');
echo 'Extension: '.$pathinfo['extension'];
?>
will produce:
Extension: gz
and not tar.gz
03-Dec-2004 04:39
If you want only the file extension, use this:
<?php
$extension = substr(strrchr($filename, "."), 1);
?>
This is many times faster than using pathinfo() and getting the value from array.

Further to my previous post.
This affects servers that run PHP as a cgi module
If you have your own server:
You can use the AcceptPathInfo directive to force the core handler to accept requests with PATH_INFO and thereby restore the ability to use PATH_INFO in server-side includes.

And, of course, to account for the problem noted in the first post whereby calling a directory, not a file, messes with the output of pathinfo(), you can include the following test:
if($pathinfo[extension] == "") {
$deep++;
}

Here's a neat wee function to grab the relative path to root (especially useful if you're using mock-directories to pass variables into scripts with mod_rewrite). The function simply iterates through every occurence of "/" within the REQUEST_URI environment variable, appending "../" to the output for every instance:
<?php
function path_to_root($path) {
$pathinfo = pathinfo($path);
$deep = substr_count($pathinfo[dirname], "/");
$path_to_root = "./";
for($i = 1; $i <= $deep; $i++) {
$path_to_root .= "../";
}
return $path_to_root;
}
path_to_root($REQUEST_URI);

If you run this on a directory, basename is the last directory in the path, dirname is the path before the final directory and extension is empty.
