看代碼就會(huì)的小例子:php合并js請(qǐng)求

復(fù)制代碼 代碼如下:

//頁(yè)面保存為js.php
//前臺(tái)請(qǐng)求范例?f=1,2
//請(qǐng)求1.js,2.js兩個(gè)文件

header("Expires: " .gmdate("D, d M Y H:i:s",time()+86400*30). " GMT");

if($_GET['f'])

 $url = parse_url($_SERVER['REQUEST_URI']);

 $arr_f = array_unique(explode(',',preg_replace("http://.+///",'',$_GET['f'])));

 foreach($arr_f as $v)
 {
  if(!empty($v))
  {
   include('./'.$v.'.js');
   echo "/n";
