PHP closedir Function – Closing Directory Handles

The closedir function in PHP closes an opened directory handle, which must have been obtained via opendir(). It takes a resource parameter $dir_handle and returns TRUE on success or FALSE on failure.

Parameters $dir_handle – the directory stream resource opened by opendir(). If omitted, the most recently opened handle is assumed.

Return value

Returns TRUE on success, FALSE on error.

Example

<?php
$dir = "/etc/php7/";
// Open a known directory, read directory into variable and then close
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        $directory = readdir($dh);
        closedir($dh);
    }
}
?>
