Are there any potential pitfalls to be aware of when using PHP to control a game server?

One potential pitfall when using PHP to control a game server is the risk of security vulnerabilities if input validation and sanitization are not properly implemented. To mitigate this risk, always validate and sanitize user input to prevent SQL injection, cross-site scripting, and other common attacks. 

// Example of validating and sanitizing user input in PHP
$user_input = $_POST['user_input'];

// Validate input
if (!filter_var($user_input, FILTER_VALIDATE_INT)) {
    // Handle invalid input
    die("Invalid input");
}

// Sanitize input
$sanitized_input = htmlspecialchars($user_input);

// Now you can safely use the sanitized input in your game server logic
