singleton
This is a singleton static proxy generator that I use in several projects instead of creating true Singletons. It was inspired by Alain Schlesser’s post on Singletons.
I’ve moved this library into it’s own repository so that I will be better able to include it via composer.
I have written it to work with PSR-4.
composer require afragen/singleton:dev-master
When using this Singleton class in your project you will create an array of class instances.
Usage
@param string $class_name
@param object $caller Originating object.
@param null|array|\stdClass $options
Singleton::get_instance( $class_name, $calling_class, $options );
This will usually be called as follows.
Singleton::get_instance( 'MyClass', $this );
The class object created will also pass the calling object as $instance[$class_name]->caller.
I do my best to automatically determine the namespace of the class. If the class is in a subfolder of src it will need to be designated in the call as follows.
If PSR-4 is set for the src directory and the class lives in src/MySubDir/MyClass the corresponding call would be as follows.
Singleton::get_instance( 'MySubDir\MyClass', $this );
I’m still learning how to properly set up using composer so this may be updated along the way.
