Maybe this code may help you getting into it?

<?php

class simpleHttpSocket {

public function sendHttpRequest($host,$filename,$port=80,$timeout=1,$x=0,$result=array()) {
    $header  = 'GET /'.$filename.' HTTP/1.1'.PHP_EOL;
    $header .= 'Host: '.$host.PHP_EOL;
    $header .= 'Connection: close'.PHP_EOL;
    $header .= 'User-Agent: Simple(php-general@xxxxxxxxxxxxx)'.PHP_EOL;
    $header .= "Referer: http://test-server.tld/".PHP_EOL.PHP_EOL;
    $socket=@fsockopen($host, $port, &$errno, &$errstr, $timeout);
    $result[-1]='';
    if (!$socket){
      trigger_error('Connection timeout',E_USER_NOTICE);
      $result["errno"]  = $errno;
      $result["errstr"] = $errstr;
      return $result;
    }
    fputs($socket, $header);
    while (!feof($socket)) {
      $result[$x++] = fgets($socket, 128);
      if (preg_match('/^Location:/',$result[$x-1])) {
        return $result[$x-1];
      }
      flush();
    }
    return $result;
  }
}

$post     = new simpleHttpSocket;
$host     = 'www.example.com';
$filename = '';  // leave empty for index file or else:
// $filename = 'image.jpg';
$file     = $post->sendHttpRequest($host,$header,80,2);

// Output
while(list($k,$v)=each($file)) {
  echo $v.'<br/>';
}

?>

Btw., when you use file_get_contets, is there a good way to tell the script
to stop recieving the file after let's say 2 seconds - just in case the
server is not reachable - to avoid using fsockopen?

       How have you been trying to do it so far?

       There are a couple of ways. file_get_contents() and fopen()
       will work on URL's if the right ports are open.

       Most usually though cURL is used for this sort of thing.

I think you're over-complicating things by using fsockopen(). Try one of
the functions I mentioned in my last email

I agree with Ashley, use one of the other options and then parse the
response to get the part of the page you'd like to work with.
