Getting end directory name

[macca_25]

Hi all,
How do i get the end directory name? ie. in the below example i want $file to only echo etc , not /cool/etc

<?php
$path = "/cool/etc/file.php";
$file = dirname($path);
echo $file;
?>

Cheers,
macca

$path = "/cool/etc/file.php";
$file = strrchr(dirname($path), "/");
echo $file;

rtrim the / if you need to.
