এখানে একটি উদাহরণ ফাংশন:
<?php
/**
* Checks if a folder exist and return canonicalized absolute pathname (long version)
* @param string $folder the path being checked.
* @return mixed returns the canonicalized absolute pathname on success otherwise FALSE is returned
*/
function folder_exist($folder)
{
// Get canonicalized absolute pathname
$path = realpath($folder);
// If it exist, check if it's a directory
if($path !== false AND is_dir($path))
{
// Return canonicalized absolute pathname
return $path;
}
// Path/folder does not exist
return false;
}
