How can error reporting and debugging techniques be used effectively in PHP to troubleshoot socket connection issues?

When troubleshooting socket connection issues in PHP, error reporting and debugging techniques can be used effectively by enabling error reporting, checking for errors in the socket connection functions, and using tools like Wireshark to analyze network traffic. Additionally, using try-catch blocks can help catch and handle any exceptions that may occur during the socket connection process. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Create a socket connection
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
    $error = socket_last_error();
    echo "Socket creation failed: " . socket_strerror($error);
}

// Connect to a remote server
$result = socket_connect($socket, '127.0.0.1', 80);
if ($result === false) {
    $error = socket_last_error();
    echo "Socket connection failed: " . socket_strerror($error);
}

// Close the socket connection
socket_close($socket);
?>
