What potential pitfalls should be considered when configuring license management in PHP applications, particularly when dealing with database manipulations for client-specific configurations?

When configuring license management in PHP applications, potential pitfalls to consider include ensuring secure storage of license keys, implementing proper validation mechanisms to prevent unauthorized access, and handling database manipulations for client-specific configurations carefully to avoid data leakage or corruption. 

// Example of securely storing license keys in PHP using environment variables
$licenseKey = getenv('LICENSE_KEY');

if (!$licenseKey) {
    die('License key not found.');
}

// Validate license key before proceeding with application logic
if (!validateLicenseKey($licenseKey)) {
    die('Invalid license key.');
}

// Proceed with application logic

function validateLicenseKey($key) {
    // Add your validation logic here
    return true; // Return true if the key is valid, false otherwise
}
