How can PHP beginners effectively troubleshoot socket connection issues?

To troubleshoot socket connection issues in PHP, beginners can start by checking the server's firewall settings to ensure the port being used is open. They can also verify that the server is listening on the correct IP address and port. Additionally, beginners should check for any errors in their PHP code that may be causing the connection problem. 

<?php
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
    echo "Failed to create socket: " . socket_strerror(socket_last_error());
} else {
    $result = socket_connect($socket, '127.0.0.1', 8080);
    if ($result === false) {
        echo "Failed to connect to server: " . socket_strerror(socket_last_error($socket));
    } else {
        echo "Socket connection successful!";
        socket_close($socket);
    }
}
?>
