What are the potential pitfalls of using PHP_Shell in a production environment?

Potential pitfalls of using PHP_Shell in a production environment include security vulnerabilities, as it allows for direct execution of PHP code which can be exploited by malicious users. It also poses a risk of accidental execution of harmful code due to its interactive nature. To mitigate these risks, it is recommended to restrict access to PHP_Shell and closely monitor its usage.

// Restrict access to PHP_Shell by checking for a specific token in the query string
if ($_GET['token'] !== 'secure_token') {
    die('Access denied');
}

// Your PHP_Shell code here
