Re: [PHP] web sniffer

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([email protected])'.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/>';
}

?>
