用 PHP文件引入css样式

html：

<link rel="stylesheet" type="text/css" href="http://www.mysite.com/path/?index.css,common.css">

php:

$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;
