script standar php ga jalan euy.. malah Fatal error: Call to undefined function socket_create()

 function send(){

 

 $server_ip = "192.168.0.255";

 $server_port = 43278;

 $beat_period = 5;

 $message = " udp sent";



 if ($socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP)) {



 socket_sendto($socket, $message, strlen($message), 0, $server_ip, $server_port);

 

 } 

 redirect($this->agent->referrer());

 }
