$filename = $_GET; foreach($filename as $key => $value){ $filenameArr = $key; } $filenameArr = explode(',' , $filenameArr); $files = array(); if(count($filenameArr) > 1){ foreach($filenameArr as $key => $value){ $arr = explode('_', $value); $files[] = $arr[0].'.'.$arr[1]; } }else{ $arr = explode('_', $filenameArr[0]); $files[] = $arr[0].'.'.$arr[1]; } $context = stream_context_create( array( "http" => array( "header" => "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36", ) ) ); //css声明 header('Content-type: text/css'); $content = ''; foreach($files as $key => $value){ $content .= iconv("utf-8", "gb2312",file_get_contents('http://www.mysite.com/path/to/' . $value, false, $context)); } echo $content;
