Knowing about Design patters is very essential in software designing and development, here in this post i am gonna write about singleton pattern, basically it is commonly used most useful well know pattern, it allows(create) only one instance to the given class on your script so we can avoid creating multiple instances. With this pattern we can use same instance of the class over and over in the script(we can use same instance to all the methods). we use global static variable to store the instance of class in singleton pattern. The best Example for singleton pattern is Database Connection object. see the bellow example script for better understanding, still if you any questions you can ask me via comment box.
