php - What is the appropriate value for UDP port? -


i'm creating php script listening incoming data user. idea user able send udp packet remotely browser , show on browser.

the script works fine when tested on localhost using xampp. after uploading script in server, fails bind socket connection everytime. tried port number 50000, 5000, 561, 61 , many others failing.

here's php script, taken php's website...

$socket = socket_create(af_inet, sock_dgram, sol_udp);     if ($socket == false) {         echo 'socket_create failed'.socket_strerror(socket_last_error())."\n";     }  if(!socket_bind($socket, $ip, $port)) {         socket_close($socket);         echo 'socket_bind_failed'; }     socket_recvfrom($socket, $buf, 255, 0, $from, $port); 

so, decided known udp port shown here, seems used application. question is, appropriate value udp port?
