preg_match question

FrozNic

i guess it's using preg_match...
i am trying to figure out how to write code to pull the folder name out of $_SERVER['PHP_SELF']

this is what i'm trying

	
$a =$_SERVER['PHP_SELF'];
	preg_match("/.*/(.*.php)/",$a,$matches);
	echo $matches[1];

and it doesn't seem to be doing it's job... it's saying this :
Warning: Unknown modifier '(' in C:\Apache\Apache2\htdocs\ccLive\admin\index.php on line 4

and i don't know why...

here's a quick examp of what i'm trying to do... say the results are
/cclive/admin/index.php

i'm trying to pull just 'admin' out of it..
anyway, thanks for any help

The error message is saying that it doesn't understand what the ( is for - the regexp engine thought the expression ended with the second '/' (since you used '/' to start it).

Escape the / with a \, or use some character other than / around your expression - ! say.

And it's a bit hard to tell - are you using \ or / to separate directories?

actually, i thought i was using the / to do it... i've never used the function before and the php.net/preg_match was severly hard to understand how the function even works... i just need to know how to write it i guess, or the structure of how pregmatch works to do it... thanks for any reply

you don't need to use / as delimiter, but if you do, you have to escape it whenever it is contained in the pattern.

one way to find the directory might be:

/cclive/admin/index.php

preg_match("#/([^/]+)/[^/]+.php#",$a,$matches);

explode might be an option too?
