opendir

(PHP 3, PHP 4, PHP 5)

Opens up a directory handle to be used in subsequent
closedir(), readdir(), and

For a description of the context parameter,
refer to the streams section of
the manual.

Returns a directory handle resource on success, or
FALSE on failure.

If path is not a valid directory or the
directory can not be opened due to permission restrictions or
filesystem errors, opendir() returns FALSE and
generates a PHP error of level E_WARNING. You can suppress the error output of
opendir() by prepending
‘@’ to the
front of the function name.

    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}
