Converting ereg expressions to preg

I want to change this line with preg_match but it doesn't works.

if ($file != "." && $file != ".." && !eregi(".jpg".$thumbext."$",$file) && eregi(".jpg$",$file)){

I tried:

if ($file != "." && $file != ".." && !preg_match(".jpg".$thumbext."$",$file) && preg_match(".jpg$",$file)){

How it should be?

Thanks!

preg requires delimiters:

preg_match('/.jpg'.$thumbex.'$/',$ile)
