What is the Singleton design pattern in laravel?

The Singleton Design Pattern in Laravel is one where a class presents a single instance of itself. It is used to restrict the instantiation of a class to a single object. It is useful when only one example is required across the system. When used properly, the first call shall instantiate the object. After that, Laravel shall return all calls to the same instantiated object.

When working with an application that requires multiple instances of an object, it can be hard to manage them all and ensure another part of your codebase is not changing them.

There are many ways you could handle this issue:

• Use a static variable inside your class and update it manually each time you want to use it
• Use a global variable and check if it's set before using it
• Use dependency injection (you'll need this if you want to inject services into your classes)
