Singleton Classes in PHP 1.0 Description
Description: In this tutorial we'll learn how to create and use singleton classes. A singleton class is a class that can be instantiated only once. This is may be useful when only one object of certain class is needed to coordinate across your system. While it may not come up frequently, it can be a useful technique when it simply doesn't make sense to have more than one instance of a class.

To achieve this target we cannot instantiate it directly using the new keyword. Instead, we must use a static method of the class to create and access the instance.
The key steps in creating singleton classes are following:

- Prevent direct instantiation by making the contructor private (optional)
- Store the only instance of the class as a static property of the class.
- Provide a static method to access the instance. The instance is created the first time this method is called.
