PHP根據傳入參數合並多個JS和CSS文件的簡單實現

HTML（使用方法）：
復制代碼 代碼如下:
<link rel="stylesheet" type="text/css" href="cssmin.php?get=base,style1,style2,global&path=css/&v=20131023" />
<script type="text/javascript" src="jsmin.php?get=jquery-1.6.4.min.js,minjquery.js,minjquery.ui.js,test.js,global.js&path=js/&v=20131023"></script>
PHP：
復制代碼 代碼如下://輸出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);

 // 刪除單行注釋
 $str = preg_replace("/\/\/\s*[a-zA-Z0-9_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*/", "", $str);
 // 刪除多行注釋
 $str = preg_replace("/\/\*[^\/]*\*\//s", "", $str);

 echo $str;
}

//輸出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");
 }
 $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;
}
只是個簡單原型，沒有封裝。另外，合並後的文件記得配合緩存。
