class Database { public static $connection; public static function connect(){ self::$connection = new mysqli('localhost', 'user', 'password', 'database'); } } Database::connect();In this example, we have defined a database class that contains a static variable ($connection) and a connect() method that creates a new MySQLi object and stores it in the static variable. This code uses the mysqli package library for connecting to the MySQL database. Overall, PHP static connection makes it easier to connect to a database and enables better database management. If you are using PHP to connect to a database, consider using a static connection for improved performance.
