Configuring composer.json Define your package properties and setup PSR-4 autoloading.
A central PHP application that stores valid licenses in a database and exposes a secure REST API to validate, activate, or deactivate keys.
CREATE TABLE `licenses` ( `id` INT AUTO_INCREMENT PRIMARY KEY, `license_key` VARCHAR(64) NOT NULL UNIQUE, `customer_email` VARCHAR(255) NOT NULL, `status` ENUM('active', 'inactive', 'suspended', 'expired') DEFAULT 'inactive', `activated_domain` VARCHAR(255) DEFAULT NULL, `expires_at` DATETIME NOT NULL, `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; Use code with caution. Step 2: The Server API Script ( verify.php )
If you want to keep your verification logic hidden from the public, use a private GitHub repository. You must generate a on GitHub with repo permissions, then configure Composer on your target machine: php license key system github install
For standalone applications, providing a curl-to-bash script allows users to pull production-ready releases directly from GitHub using a single terminal command.
: A simple, robust class for generating serial-number-style product keys with custom templates.
Open your terminal and navigate to your web server directory (e.g., /var/www/html ). Clone the repository directly from GitHub: git clone https://github.com cd repo-name Use code with caution. Step 2: Install Dependencies via Composer CREATE TABLE `licenses` ( `id` INT AUTO_INCREMENT PRIMARY
For package-based systems like , use Composer: composer require masterix21/laravel-licensing Use code with caution. Copied to clipboard 2. Run Migrations & Config
