rmdir
(PHP 4, PHP 5)
rmdir — Delete directory
Report a bug Description
bool rmdir (string $dirname)
Try to delete the directory specified by dirname. The directory must be empty and must have appropriate permissions. Returns TRUE on success, or FALSE on failure.
Note: Since PHP 5.0.0 rmdir() can also be used with certain URL wrapping protocols. See the list of Supported Protocols and Wrappers to see which URL wrapping protocols rmdir() supports.
Note: Support for context (Context) was added in PHP 5.0.0. See the Stream function for a description of context.
Note: When safe mode is enabled, PHP will check whether the directory being scripted has the same UID (owner) as the script being executed when executing the script.
See mkdir() and unlink().

<?php 
function rrmdir($dir) { 
if (is_dir($dir)) { 
$objects = scandir($dir); 
foreach ($objects as $object) { 
if ($object != "." && $object != "..") { 
if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object); 
} 
} 
reset($objects); 
rmdir($dir); 
} 
}
