Is it recommended to use a strict interface for database interactions in PHP, such as defining a class with specific implementations for different database systems?

It is recommended to use a strict interface for database interactions in PHP to ensure consistency and maintainability across different database systems. By defining a class with specific implementations for different database systems, you can easily switch between databases without changing the core logic of your application. 

interface DatabaseInterface {
    public function connect();
    public function query($sql);
    public function fetch($result);
}

class MySQLDatabase implements DatabaseInterface {
    public function connect() {
        // MySQL connection logic
    }

    public function query($sql) {
        // MySQL query logic
    }

    public function fetch($result) {
        // MySQL fetch logic
    }
}

class PostgreSQLDatabase implements DatabaseInterface {
    public function connect() {
        // PostgreSQL connection logic
    }

    public function query($sql) {
        // PostgreSQL query logic
    }

    public function fetch($result) {
        // PostgreSQL fetch logic
    }
}
