刚与大家分享了PHP解析 KU6视频真实地址，本文再与大家分享一下PHP解析土豆FLV真实地址，方法如下：

要求：服务器必须支持CURL或fsockopen。

详细代码：

<?php
function curl_get_contents($url)
{
if(!function_exists(‘curl_init’)) {
return false;
} else {
$user_agent = $_SERVER[‘HTTP_USER_AGENT’];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
$content = curl_exec($ch);
$errormsg = curl_error($ch);
curl_close($ch);
if($errormsg != ”) {
echo $errormsg;
return false;
}
return $content;
}
}

function fsock_get_contents($url)
{
if(!function_exists(‘fsockopen’)) {
return false;
} else {
$user_agent = $_SERVER[‘HTTP_USER_AGENT’];
$url = eregi_replace(‘^http://’, ”, $url);
$temp = explode(‘/’, $url);
$host = array_shift($temp);
$path = ‘/’.implode(‘/’, $temp);
$temp = explode(‘:’, $host);
$host = $temp[0];
$port = isset($temp[1]) ? $temp[1] : 80;
$fp = @fsockopen($host, $port, $errno, $errstr, 30);
if ($fp){
@fputs($fp, “GET $path HTTP/1.1rnHost: $hostrnAccept: */*rnReferer:$urlrnUser-Agent: $user_agentrnConnection: Closernrn”);
}
$content = ”;
while ($str = @fread($fp, 4096)){
$content .= $str;
}
@fclose($fp);
//Redirect
if(preg_match(“/^HTTP/d.d 301 Moved Permanently/is”, $content)){
if(preg_match(“/Location:(.*?)rn/is”, $content, $murl)){
return fsock_get_contents($murl[1]);
}
}
//Read contents
if(preg_match(“/^HTTP/d.d 200 OK/is”, $content)){
preg_match(“/Content-Type:(.*?)rn/is”, $content, $murl);
$contentType = trim($murl[1]);
$content = explode(“rnrn”, $content, 2);
$content = $content[1];
}
return $content;
}
}

function get_page_contents($url)
{
$content = ”;
if(function_exists(‘curl_init’)) {
$content = curl_get_contents($url);
} elseif (function_exists(‘fsockopen’)) {
$content = curl_get_contents($url);
} else echo “函数 curl_init 和 fsockopen 都为关闭,请至少打开一个.”;
return $content;
}

function td_id($url)
{
if(preg_match(‘/http://hd.tudou.com/program/([A-Za-z0-9-_]+)/’, $url, $hd)) {
$target_url = “http://hd.tudou.com/program/”.$hd[1];
} elseif (preg_match(‘/http://www.tudou.com/programs/view/([A-Za-z0-9-_]+)/’, $url, $td)) {
$target_url = “http://www.tudou.com/programs/view/”.$td[1];
}

$content = get_page_contents($target_url);
preg_match(‘/iid.*?([0-9]+)/’, $content, $tudou);
$tudou_id = $tudou[1];

return $tudou_id;
}

function get_flv($video_id)
{
$flv_link = “”;

$target_url = ‘http://v2.tudou.com/v2/cdn?id=’.$video_id;

$video_data = get_page_contents($target_url);

preg_match(‘/<f w=”([0-9]+)”/’, $video_data, $match_num);
preg_match(‘/http://(.*?)?/’, $video_data, $match_url);
preg_match(‘/key=([w]+)/’, $video_data, $match_key);
$flv_link = ‘http://’.$match_url[1].’?’.$match_num[1].’&key=’.$match_key[1].’&id=tudou’;
return $flv_link;
}
?>
