preg_replace out CSS comments?

Question

I\'m writing a quick preg_replace to strip comments from CSS. CSS comments usually have this syntax:

/* Development Classes*/
/* Un-comment me for easy testi

I had the same issue. To solve it, I first simplified the code by replacing "/ASTERIX" and "ASTERIX/" with different identifiers and then used those as the start and end markers.

$code = str_replace("/*","_COMSTART",$code);
$code = str_replace("*/","COMEND_",$code);
$code = preg_replace("/_COMSTART.*?COMEND_/s","",$code);

The /s flag tells the search to go onto new lines
