What resources or tutorials would you recommend for someone looking to improve their PHP skills for socket server development?

To improve PHP skills for socket server development, I recommend exploring online resources such as the official PHP documentation, tutorials on websites like W3Schools or TutorialsPoint, and books like "PHP and MySQL Web Development" by Luke Welling and Laura Thomson. Additionally, joining online communities or forums dedicated to PHP development can provide valuable insights and tips from experienced developers.

<?php
// Example PHP code for creating a basic socket server

$host = "127.0.0.1";
$port = 12345;

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($socket, $host, $port);
socket_listen($socket);

echo "Socket server started on $host:$port\n";

while (true) {
    $client = socket_accept($socket);
    $message = "Hello, client!";
    socket_write($client, $message, strlen($message));
    socket_close($client);
}
