CSS parser using PHP

Here's my css link for images:

background-image:url(images/background.gif);

I just want to add some: ../ to change the directory. So my code will look like this:

background-image:url(../images/background.gif);

How will I do that? I don't need a whole CSS parser just the code to add the ../ for the开发者_运维技巧 images...

$css = str_replace("url(images/", "url(../images/", $css);

Could you not just do a find and replace in your CSS for "(images/" and replace with "(../images/" ??

You must use regex to parse css correctly
