How can PHP scripts be protected from piracy and unauthorized distribution?

To protect PHP scripts from piracy and unauthorized distribution, you can use techniques such as obfuscation, licensing agreements, and encryption. Obfuscation involves making the code more difficult to understand, licensing agreements can restrict usage to authorized users only, and encryption can prevent unauthorized access to the code. 

// Example of using licensing agreements to protect PHP scripts

$license_key = "YOUR_LICENSE_KEY_HERE";

function check_license($license_key) {
    $valid_keys = array("VALID_KEY_1", "VALID_KEY_2", "VALID_KEY_3"); // List of valid license keys
    if (in_array($license_key, $valid_keys)) {
        return true; // Valid license key
    } else {
        return false; // Invalid license key
    }
}

if (!check_license($license_key)) {
    die("Unauthorized use of this script."); // Display error message if license key is invalid
}

// Rest of your PHP script here
