php实现对css文件进行压缩和解压缩

时间：2022-06-24 17:32:28 编辑：袖梨来源：一聚教程网

将css代码压缩能够减小文件的体积，从而减小了网络传输量和带宽占用，减小了服务器的处理的压力

源码：

代码如下

复制代码

$string = trim(stripslashes($_POST['code'])); //stripslashes()函数删除转义字符（反斜杠）

if(!empty($string)){

if($_POST['method'] == '压缩' ){

$string = css_compress($string);

}elseif($_POST['method'] == '解压缩' ){

$string = css_decompress($string);

}

}else{

$string = '';

}

function css_compress($string){

//压缩

$string = str_replace("rn","",$string); //首先去掉换行

$string = preg_replace("/(s*{s*)/","{",$string);

$string = preg_replace("/(s*;s*}s*)/","}",$string); //去掉反括号首位的空格和换行，和最后一个;

$string = preg_replace("/(s*;s*)/",";",$string);

return $string;

}

function css_decompress($string){

//解压

$string = css_compress($string); //为了效果更好，解压前，先压缩至最简状态

$string = str_replace("{","rn{rnt",$string);

$string = str_replace("}","rn}rnrn",$string);

$string = str_replace(";",";rnt",$string);

$string = str_replace("*/","*/rn",$string);

return $string;

}

请将css代码粘贴到下面框中,然后选择压缩/解压缩
