What legal measures can PHP developers take to prevent unauthorized distribution of their software?

To prevent unauthorized distribution of PHP software, developers can implement licensing agreements, obfuscate their code, and use digital rights management (DRM) tools. Additionally, developers can utilize encryption techniques to protect their software from being copied or distributed without permission. 

// Example code snippet for implementing licensing agreements in PHP

// Check if a valid license key is provided
function checkLicenseKey($licenseKey) {
    // Implement logic to validate the license key
    // Return true if the license key is valid, false otherwise
}

// Usage example
$licenseKey = $_POST['license_key'];
if (checkLicenseKey($licenseKey)) {
    // Proceed with executing the software
} else {
    // Display an error message or restrict access to the software
}
