finding absolute path to current script / without current script

[traq]

Hi,

I need to figure out how to determine the absolute path to the directory containing the currently executing script:

<?php
$absolute = $_SERVER['DOCUMENT_ROOT'].$_SERVER['PHP_SELF'];
?>

will get me the path including the file name, but I want it without. Like so:

www.example.com/path/to/

and not like so:

www.example.com/path/to/file.php

If you have the answer, I'd love to hear it

PHP might have something built in for this, but here's something that should work:

You can use one $_SERVER command, instead of two in this instance

<?php

$end = strrpos($_SERVER['SCRIPT_FILENAME'], '/'); // Finds last slash

echo substr($_SERVER['SCRIPT_FILENAME'], 0, $end + 1); 

// returns file path with / added on the end, remove + 1 to take this out

?>

hey, cool. I was up late last night looking for a built-in PHP function, but couldn't figure it out. Thanks!
