What are some recommended practices for protecting PHP scripts from unauthorized use and distribution?

One recommended practice for protecting PHP scripts from unauthorized use and distribution is to use licensing and encryption techniques. By encrypting your PHP code and implementing a licensing system, you can prevent unauthorized users from accessing and distributing your scripts. 

// Example of encrypting PHP code using ionCube
// Install ionCube Loader on your server to run encrypted scripts
// Generate an encrypted version of your PHP script using ionCube Encoder

// Example of implementing a licensing system
$license_key = "your_license_key_here";

if ($_GET['key'] !== $license_key) {
    die("Unauthorized access.");
}

// Your PHP script code here
