How can one ensure the security and reliability of executing PHP files through external scripts like batch files or JavaScript?

To ensure the security and reliability of executing PHP files through external scripts like batch files or JavaScript, it is important to validate and sanitize user input to prevent any malicious code injection. Additionally, limiting the permissions of the PHP files being executed and using secure communication protocols can help enhance security. 

<?php
// Validate and sanitize user input
$input = $_GET['input'];
$sanitized_input = filter_var($input, FILTER_SANITIZE_STRING);

// Limit permissions of the PHP file
chmod("my_script.php", 0755);

// Secure communication protocol
if ($_SERVER["HTTPS"]) {
    // Execute PHP file
    include("my_script.php");
} else {
    echo "Access denied. Please use a secure connection.";
}
?>
