正则表达式使用php将文件路径替换为字符串中的文件名

Question

I've got a css string like this :

$string = "div#test {background: url(images/test.gif); width:100px; } div#test2 {background: url(../images/test2.gif); } ";

Basically I want to able to replace everything between url () to just the filename. So that it eventually looks like :

$string = "div#test {background: url(test.gif); width:100px; } div#test2 {background: url(test2.gif); } ";

Sort of like applying basename but for relative urls and for all such instances.

Any ideas ?

Try this:

EDIT: I fixed the regex

<?php 

$string = "div#test {background: url(images/test.gif); width:100px; } div#test2 {background: url(../images/test2.gif); } ";
$output = preg_replace('/([\.\w\/]*\/)/', '', $string);

var_dump($output);
string(93) "div#test {background: url(test.gif); width:100px; } div#test2 {background: url(test2.gif); } "
?>
