Singleton

A singleton is a class that can only be instantiated once. It is often used to manage global state in a program. This can be useful for allowing a single global instance of a class to be shared across the entire program.

note

If you are working with the Mantle Framework you should use the Container's singleton method to create a singleton instance of a class.

Usage‚Äč

To create a singleton class, you can use the following pattern:

namespace App;

use Mantle\Support\Traits\Singleton;

class Example_Class {
use Singleton;

protected function __construct() {
// Your constructor code here
}
}

Then you can instantiate the class like this:

$instance = Example_Class::instance();

The instance method will always return the same instance of the class.
