Read data using the waitForResponse () method

Example code:

functionSend_socket ($req,$ip,$port){    $byte=NewBytes (); $req _bytes=$byte->getbytes ($req); $req _trans=$byte->TOSTR ($req _bytes); $req _length=strlen($req _trans); $pack=Pack("a{$req _length}",$req _trans); $socket= Socket::Singleton (); $socket->connect ($ip,$port); $socket->sendrequest ($pack); $socket _result=$socket-waitForResponse (); $socket-disconnect (); return $socket _result;}Var_dump(Send_socket ("Test", "127.0.0.1", 443));
