PHP socket_create , problem with response (proxy server creating)

[lopez86100]

Hi all !!

 

I'm trying to write simple proxy server, I get header but I can't send a response, I'm trying to fix it for 3 days with no result. I tried to use socket_sendto() but there was an error (I think PHP BUG) .I don't have any more ideas how to solve it. Can anybody help me. ?Here is the code:

 

 <?php
error_reporting(E_ALL);
set_time_limit(0);
$value1="";
  $addr = my_ip();
  
$local_port=81;
  function my_ip($dest='64.0.0.0', $port=80)
  {
    $socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
    socket_connect($socket, $dest, $port);
    socket_getsockname($socket, $addr, $port);
    socket_close($socket);
    return $addr;
  }
  
  
  
  
  while(1){
  

$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
socket_bind($socket,NULL,81);
socket_listen($socket);

#echo "Waiting for a connection\n";
$conn = false;
switch(socket_select($r = array($socket), $w = array($socket), $e = array($socket), 60)) {
    case 2:
       # echo "Connection refused\n";
        break;
    case 1:
       # echo "Connection accepted\n";
        $conn = socket_accept($socket);
        
        break;
    case 0:
     ##   echo "Connection timed out\n";
        break;
}
   
   
if ($conn !== false) {
$buffer="";
$buffer1="";
while($buffer=socket_read($conn,512,PHP_BINARY_READ)){
$buffer1.=$buffer;
}
   
   
   
echo $buffer=$buffer1;
   
   
   preg_match("@\s*([post|GET])\s*(http[^\s]*).*@si",$buffer,$address);
   
   

   

  $address=$address[2];
   
   if(preg_match("@\s*POST\s*http@si",$buffer,$new)){



$method="POST";


}   if(preg_match("@\s*GET\s*http@si",$buffer,$new)){



$method="GET";


}
   

   
   
   if($method=="GET"){

$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiejar21"."");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiejar21"."");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_MAXREDIRS, 15);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
@curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_URL,$url=$address);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 25);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$echo = curl_exec($ch);


$addr1="";
$port1="";

socket_getpeername ($conn,&$addr1,&$port1);


/*it doesnt't work if I am giving a handle "$socket" there is an error , when I am giving a "$conn" there is no error but in a browser nothing happens. As you can see I gave in curl HEADER included so it should be sent with all content. It seems that this function doesn't word properly in this case.*/


socket_write ($conn, $echo, strlen ($echo));







curl_close($ch);

}elseif($method=="POST"){

}else{
}
   }


socket_close($socket);








}
