php压缩多个CSS/JS文件

1:压缩css

<?php   
header(&#39;Content-type: text/css&#39;);   
ob_start("compress");   
function compress($buffer) {   
/* remove comments */   
$buffer = preg_replace(&#39;!/*[^*]**+([^/][^*]**+)*/!&#39;, &#39;&#39;, $buffer);   
/* remove tabs, spaces, newlines, etc. */   
$buffer = str_replace(array("rn", "r", "n", "t", &#39;  &#39;, &#39;    &#39;, &#39;    &#39;), &#39;&#39;, $buffer);   
return $buffer;   
}     
   
/* your css files */   
include(&#39;galleria.css&#39;);   
include(&#39;articles.css&#39;);
ob_end_flush();

使用:

<link href="compress.php" rel="stylesheet" type="text/css" /><span id="tester">test</span>

2:压缩js,利用jsmin类:

header('Content-type: text/javascript');   
require 'jsmin.php';   
echo JSMin::minify(file_get_contents('common.js') . file_get_contents('common2.js'));  //phprm.com
