{
//Send information
@fputs($fp, $req[0]);
//If you need to receive information returned by the server, then
if($req [1])
{
//Receive information
while($result = @fgets($fp, 1024))
{ if(substr($result,3,1) == " ") { break; }
}
if (!strstr($req[1],substr($result,0,3)))
{ $result_str.=$req[2].$result."
