Unable to do telnet to php socket code -


i created php program listen port.here php code

<?php  if(!($sock = socket_create(af_inet, sock_dgram, 0))) {     $errorcode = socket_last_error();     $errormsg = socket_strerror($errorcode);     die("couldn't create socket: [$errorcode] $errormsg \n"); } echo "socket created \n";   if( !socket_bind($sock, "192.168.0.177" , 5060) ) {     $errorcode = socket_last_error();     $errormsg = socket_strerror($errorcode);     die("could not bind socket : [$errorcode] $errormsg \n"); } echo "socket bind ok \n";  while(1) {     echo "waiting data ... \n";      $r = socket_recvfrom($sock, $buf, 512, 0, $remote_ip, $remote_port);      echo $buf; }  ?>

but when telnet 192.168.0.177 5060 message 

could not open connection host on port 5060

i checked telnet service , running fine.

that's because open udp socket, , telnet uses tcp.
