How would you use static properties in a class representing a database connection to ensure there is only one connection instance?
- Implement a singleton pattern by allowing only one instance of the class and store the connection as an instance property.
- Utilize a static property to store the connection instance and check its existence before creating a new one.
- Use a separate connection manager class with a static property to handle the singleton behavior.
- Implement a global variable to store the connection instance and update it as needed.
To ensure there is only one instance of a database connection, using a static property within the class is appropriate. This static property can store the connection instance, and before creating a new connection, you can check if the static property already holds a valid connection. This approach aligns with the singleton pattern, ensuring a single point of access to the connection.
