I have written following function in functions.php file and trying to access it through jquery ajax.

This works fine.

function data_fetch(){
    echo "working";

But this doesn't show any error and prints nothing

function data_fetch(){
//  var_dump($_POST);
    echo "working";
    $host    = "x.x.x.x";
    $port    = 35001;
    $message = json_encode($_POST);
    $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
    $result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");  
    socket_write($socket, $message, strlen($message)) or die("Could not send data to server\n");
    $result = socket_read ($socket, 1024) or die("Could not read server response\n");
    echo "Reply From Server  :".$result;

is this way right? if no then what are another way to do socket programming with WordPress?

  • There must be an error somewhere. Have you checked the web server logs? – Rup Jun 18 '17 at 11:44

    in log it says that call to undefined function socket_create() but i have enabled sockets in my php ini file – JAGGADAKU Jun 18 '17 at 17:02

The answer is "No", there is nothing in wordpress that may interfere with usage of PHP socket API.
