Compress CSS with PHP

gistfile1.php

Minify.css.php?f=style.css

<?php
//重定义header
ob_start ("ob_gzhandler");
header("Content-type: text/css; charset=UTF-8");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 ;
$ExpStr = "Expires: " .
gmdate("D, d M Y H:i:s",
time() + $offset) . " GMT";
header($ExpStr);

//压缩过程
$rawCss = include($_GET[f]);
$minCss = Compress($rawCss);
echo($minCss);

?>

配置mod_rewrite之类的，把style.css请求，重定向到Minify.css.php?f=style.css
html中正常调用css文件
<link rel='stylesheet' type='text/css' href='css/style.css' />
