What are the best practices for executing PHP scripts externally in the root directory?

When executing PHP scripts externally in the root directory, it is important to ensure that the scripts are secure and do not pose a risk to your server. One best practice is to use a combination of file permissions and input validation to prevent unauthorized access and potential security vulnerabilities. 

<?php
// Check if the script is being accessed directly
if (basename(__FILE__) == basename($_SERVER["SCRIPT_FILENAME"])) {
    die("Access denied");
}

// Your PHP script code here
// Make sure to validate and sanitize any user input
// Avoid executing any external code or commands directly
?>
