@NogDogDec 04.2014 — #It's a "Singleton Pattern" approach, where only one instance of this class will exist, and any code that wants to use it would call that getInstance() method (statically), rather than making its own instantiation via "new". So that return statement is returning a reference to that one object instance, which is -- sort of recursively -- stored within the object itself via the class's $instance property.
The function
[CODE] static function getInstance(){
if (!self::$instance) {
self::$instance = new self();
}
return self::$instance;
} // end of getInstance function
I really don’t understand the the above function , can somebody really explain it to me , why the below line :
[CODE]return self::$instance;
