前言

利用PHP把所有的CSS JS 处理压缩成一个文件输出

PHP处理CSS

<?php  
    header('Content-type: text/css');  
    ob_start("compress");  
    function compress($buffer) {  
        $buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer);  
        $buffer = str_replace(array(" 
        ", "\r", "\n", "\t", '  ', '    ', '    '), '', $buffer);  
        return $buffer;  
    }  
    include('第一个CSS文件');   //例如当前PHP文件下的 ./main.js
    include('第二个CSS文件');   //复制调用更多JS文件
    ob_end_flush();  //输出压缩后的内容
?>

CSS调用

 <link rel="stylesheet" type="text/css" href="处理CSS的PHP文件地址"/>

PHP处理JS

<?php
    error_reporting(E_ALL & ~E_NOTICE);
    if(extension_loaded('zlib')){
        ob_start('ob_gzhandler');
    }
    header ("content-type:application/x-javascript; charset: UTF-8");
    header ("cache-control: must-revalidate");
    $offset = 60 * 60 * 24; //js文件的距离现在的过期时间，这里设置为一天
    $expire = "expires: " . gmdate ("D, d M Y H:i:s", time() + $offset) . " GMT";
    header ($expire);
    ob_start("compress");
    function compress($buffer) {
        $buffer = preg_replace('/\/\/.*/','', $buffer);
        $buffer = str_replace(array("
        ", "\r", "\n", "\t", '  ', '    ', '    '), '', $buffer);
        return $buffer;
    }
    include('js文件一'); //例如当前PHP文件下的main.js
    include('js文件二'); //复制调用更多JS文件
    if(extension_loaded('zlib')){
        ob_end_flush(); //输出压缩后的内容
    }
?>

JS调用

<script src="处理JS的PHP文件地址" type="text/javascript" charset="utf-8"></script>

<?php
$text = "123456789";
//保存一段文字
echo substr($text,strripos($text,"5")+1);
//输出5之后内容
echo substr($text,0,strrpos($text,"5"));
//输出5之前内容
echo substr(substr($text,0,strrpos($text,"8")),strripos(substr($text,0,strrpos($text,"8")),"5")+1);
//输出5之后8之前的内容
?>


<?php
preg_match('/.*?<p>(\d*?)<\/p>.*?/', "<p>www.svipbox.cn</p>", $res);
echo $res;
//输出 www.svipbox.cn
?>

一款垃圾分类的接口源码
