PHP获取优酷视频FLV地址

在使用Ckplayer播放视频的时候，因为要读取第三方网站的视频数据，这里就需要获取如优酷的FLV地址，则将下面的内容存储为 yk.php，并通过

yk.php?u=url(优酷的视频播放地址) 获取真实地址

<?php

if(isset($_GET['u'])) $url = safeurl($_GET['u']);

$f = 2; //默认为超清.
if($f == 1) {
$f = 'high';
} else if($f == 2) {
$f = 'super';
} else if($f == 5) {
$f = 'super2';
} else if($f == 9) {
$f = 'real';
} else {
$f = 'normal';
