PHP UDP Server with Arduino as Client -

i have programmed arduino send massage udp port 8888 when button pressed, , working fine when used third party software such socket test, trying use below php code receive massage.

the code(not code) works, result show when fatal errors , not when send massage(press button)

below sample of result(all result show , not when press button):

socket created socket bind ok waiting data ... 10.10.1.48 : 8888 --yellowwaiting data ... 10.10.1.48 : 8888 -- greenwaiting data ... 10.10.1.48 : 8888 -- yellowwaiting data ... 10.10.1.48 : 8888 -- greenwaiting data ...  fatal error: maximum execution time of 120 seconds exceeded in c:\xampp\htdocs\push\udp.php on line 38  

below code:

if(!($sock = socket_create(af_inet, sock_dgram, 0))) {     $errorcode = socket_last_error();     $errormsg = socket_strerror($errorcode);      die("couldn't create socket: [$errorcode] $errormsg \n"); }  echo "socket created \n";   if ( ! socket_set_option($sock, sol_socket, so_reuseaddr, 1))  {      echo socket_strerror(socket_last_error($sock));      exit;  } // bind source address if( !socket_bind($sock, "0.0.0.0" , 8888) ) {     $errorcode = socket_last_error();     $errormsg = socket_strerror($errorcode);      die("could not bind socket : [$errorcode] $errormsg \n"); }  echo "socket bind ok \n";  //do communication, loop can handle multiple clients while(1) {     echo "waiting data ... \n";      //receive data     $r = socket_recvfrom($sock, $buf, 512, 0, $remote_ip, $remote_port);     echo "$remote_ip : $remote_port -- " . $buf;     usleep(100000); // debuging purpose     ob_flush();     flush();     //send data client     socket_sendto($sock, "ok " . $buf , 100 , 0 , $remote_ip , $remote_port); }  socket_close($sock);
