PHP Functions
Function: dirname (PHP 3, PHP 4, PHP 5) dirname -- Returns directory name component of pathDescriptionstring dirname ( string path )Given a string containing a path to a file, this function will return the name of the directory. On Windows, both slash ( / ) and backslash ( \ ) are used as directory separator character. In other environments, it is the forward slash ( / ).
Example 1. dirname() example <?php $path = "/etc/passwd"; $file = dirname($path); // $file is set to "/etc" ?> Note: In PHP 4.0.3, dirname() was fixed to be POSIX-compliant. Essentially, this means that if there are no slashes in path , a dot (' . ') is returned, indicating the current directory. Otherwise, the returned string is path with any trailing /component removed. Note that this means that you will often get a slash or a dot back from dirname() in situations where the older functionality would have given you the empty string. dirname() has changed its behaviour in PHP 4.3.0. Check the following examples:
<?php
//before PHP 4.3.0
dirname('c:/'); // returned '.'
//after PHP 4.3.0
dirname('c:/'); // returns 'c:'
?>
dirname() has been binary safe since PHP 5.0.0 Related Function(s) |
