preg_replace help

[koolaidman52]

I'm helping a freidn out with a website for our school basketball team and we recently ran into a problem. I rushed in thinking that with my superior knowledge of all things php I would be able to solve any complex error he may have, but I can't figure out the proper way to use preg_replace() in this situaition (or if I need to use it at all).

[code]
$blah = $_SERVER['REQUEST_URI'];
// $blah is /knights%20basketball/varsity/footer.php
$blah = str_replace("/footer.php", "", $blah);
// $blah is now /knights%20basketball/varsity
//the following line of code is the problem i can't figure out what to put as the first argument.
$blah = preg_replace('', '$1', $blah);
// the /knight%20basketball/ changes so I can't just have it search and remove that.
// $blah should now just be varsity
// but it isn't
echo $blah;
[/code]

please dont direct me to the php manual that didn't help
thanks for the help

take a look at [url=http://www.php.net/preg_replace]preg_replace[/url] in the manual.

just kidding.

what are you trying to match exactly? can you be a little more specific of what you're trying to do?

cheers

well i'm getting the uri of the file which turs out to be "/knights%20basketball/varsity/footer.php" in my example. i want that cut down to "varsity"

If it's always going to be in that position:

[code]
<?php
$string = "/knights%20basketball/varsity/footer.php";
list(,,$var) = explode('/', $string);
echo $var;
?>
[/code]
