(Why does my PHP suck so much? C++ was easier than this)

I need PHP to not do anything if a string does not have something in it (in this case the value stored in $ext, which stands for extension, which means I'm playing around with files)

So if file.html ends with .html then go do this, otherwise get lost.
At the moment I'm painfully listing all the files in the if, which is what I don't want to do.

Code:
if ($file != ".htaccess" && $file != "thumbs.db" && $file != "..")

Regular Expressions maybe?

So something like

Code:
if (preg_match(".".$ext."$i", $file))


Oh and in case you don't get my fancy programming there, its the same as this:

Code:
if (preg_match(".html$i", "file.html"))


So using your cheat sheet, all files ending in .html will be used, the rest ignored.

$ = at the end of string
i = case-insensitive

Right?
(I hope)

Success? No
