How to automte a path - operations on paths

[Jitro]

Hello

First, Happy Easter.

I can't solve my small problem with a path.

<?php
echo $_SERVER['PHP_SELF'];
echo '<br />';

echo $a = dirname($_SERVER['PHP_SELF']);
echo '<br />';

echo rtrim($a,'imagesw');

?>

the result is:
/cw/draw/upload2/images/test.php
/cw/draw/upload2/images
/cw/draw/upload2/

My purpose is it obtain the third line '/cw/draw/upload2/' but not by trim function. I want to cut off the last directory. In the case above it's 'images', but what if it's not and it's sth else... How can I automate the script to get the last line i.e. '/cw/draw/upload2/'.

Thanks in advance and once again Happy Easter.

use [man]realpath/man

print realpath( dirname( $_SERVER['PHP_SELF'] ).'/../' );

Or maybe this?

$dirName = dirname(dirname($_SERVER['PHP_SELF']));
