PHP根据传入参数合并多个JS和CSS文件的简单实现

这篇文章主要介绍了PHP合并多个JS和CSS文件的简单实现,本文使用了一种比较简单的方法,重在揭示实现原理,需要的朋友可以参考下

HTML（使用方法）：

代码如下:

代码如下:

//输出JS
header ("Content-type:application/x-Javascript; Charset: utf-8");
if(isset($_GET)) {
$files = explode(",", $_GET['get']);
$str = '';
foreach ($files as $key => $val){
$str .= file_get_contents($_GET['path'].$val);
}

$str = str_replace("\t", "", $str); //清除空格
$str = str_replace("\r\n", "", $str);
$str = str_replace("\n", "", $str);

// 删除单行注释
$str = preg_replace("/\/\/\s*[a-zA-Z0-9_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*/", "", $str);
// 删除多行注释
$str = preg_replace("/\/\*[^\/]*\*\//s", "", $str);

echo $str;
}

//输出CSS
header ("content-type:text/css; charset: utf-8");
if(isset($_GET)) {
$files = explode(",", $_GET['get']);
$fc = '';
foreach ($files as $key => $val){
$fc .= file_get_contents($_GET['path'].$val.".css?6.1.3");
}
$fc = str_replace("\t", "", $fc); //清除空格
$fc = str_replace("\r\n", "", $fc);
$fc = str_replace("\n", "", $fc);
$fc = preg_replace("/\/\*[^\/]*\*\//s", "", $fc);
echo $fc;
}
