What best practices should PHP beginners follow when programming games in PHP for the SSH console?

Issue: PHP beginners programming games for the SSH console may not be familiar with best practices for efficient and secure code. To ensure a smooth development process, beginners should follow practices such as using proper error handling, sanitizing user input, and organizing code into functions for modularity and reusability. Code snippet:

php 
<?php
// Example of using proper error handling in PHP
try {
    // Your game logic here
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}

// Example of sanitizing user input in PHP
$user_input = filter_input(INPUT_POST, 'user_input', FILTER_SANITIZE_STRING);

// Example of organizing code into functions for modularity and reusability
function check_input($input) {
    // Check input logic here
}

function process_game($input) {
    // Game processing logic here
}
?>
