我需要通过代理(从运行的fsockopen代码，从远程视频文件获取大小) - I need to go through a proxy, (from a running fsockopen code that gets the size from a remote video file)

I need to go through a proxy, (from a running fsockopen code that gets the size from a remote video file)

我有一个PHP运行代码，询问远程mp4文件的文件大小，这要归功于fsockopen函数和HEAD命令。

现在，我需要将此代码移动到代理后面的其他服务器，这是通过新代理的最佳方法，并继续使用fsockopen?我真的卡住了。我不能隧道或处理两个套接字。

任何想法?谢谢你的帮助和时间。

private function filesize_remote($remotefile, $timeout=10) {
       $size = false;
       $url = parse_url($remotefile);
       if ($fp = @fsockopen($url['host'], ($url['port'] ? $url['port'] : 80), $errno, $errstr, $timeout)) {
          fwrite($fp, 'HEAD '.@$url['path'].@$url['query'].' HTTP/1.0'."'r'n".'Host: '.@$url['host']."'r'n'r'n");
          while (!feof($fp)) {
             $headerline = fgets($fp, 4096);
             if (preg_match('/^Content-Length: (.*)/', $headerline, $matches)) {
                $size = intval($matches[1]);
                break;
             }
          }
          fclose ($fp);
       }
       return $size;  
    }

无代理:

<?php
$fp = fsockopen("www.wahoo.com",80);
fputs($fp, "GET <a href='"http://www.yahoo.com/'" "
  ."title='"http://www.yahoo.com/'">http://www.yahoo.com/</a> HTTP/1.0'r'n'r'n");
$data="";
while (!feof($fp)) $data.=fgets($fp,64000);
fclose($fp);
print $data;
?>

与代理:

<?php
$ip = "1.2.3.4"; // proxy IP, change this according to your proxy setting
$port = 1234; // proxy port, change this according to your proxy setting
$fp = fsockopen($ip,$port); // connect to proxy
fputs($fp, "GET <a href='"http://www.yahoo.com/'"   "
  . "title='"http://www.yahoo.com/'">http://www.yahoo.com/</a>  "
  . "HTTP/1.0'r'nHost:www.yahoo.com:80'r'n'r'n");
$data="";
while (!feof($fp)) $data.=fgets($fp,64000);
fclose($fp);
print $data;
?>

使用代理和认证:

<?php
$ip = "1.2.3.4"; // proxy IP, change this according to your proxy setting
$port = 1234; // proxy port, change this according to your proxy setting
$fp = fsockopen($ip,$port); // connect to proxy
$login = "Alexander"; // login name
$passwd = "kiss me"; // password
fputs($fp, "GET <a href='"http://www.yahoo.com/'" "
 . "title='"http://www.yahoo.com/'">http://www.yahoo.com/</a> HTTP/1.1'r'n"
 . "Host:www.yahoo.com:80'r'n"
 . "Proxy-Authorization: Basic ".base64_encode("$login:$passwd") ."'r'n'r'n");
$data="";
while (!feof($fp)) $data.=fgets($fp,64000);
fclose($fp);
//12314
print $data;
?>
