php压缩多个CSS为一个css的代码并缓存

网学网为广大网友收集整理了，php压缩多个CSS为一个css的代码并缓存，希望对大家有所帮助！

复制代码 代码如下:
<?php
/*
Compress multiple CSS files into one and cache for an hour.

Use the same code for Javascript, but replace below "text/css" with "text/javascript" and of course make sure you include .js files instead of .css ones.
*/
ob_start("ob_gzhandler");
header("Content-type: text/css; charset: UTF-8");
header("Expires: ".gmdate("D, d M Y H:i:s", time() + 60*60)." GMT");

include(''somefile.css'');
echo "\n\n";
include(''anotherfile.css'');
echo "\n\n";

ob_flush();
