1 $this keyword refers to the instance from within the class definition
2 __autoload( ) is called whenever you try to create an object of a class that hasnt been defined
3 __autoload() function automatically includes a class file
4 __call
5 __call( ) method is called if PHP fails to find the method
6 __get( ) specifies what to do if an unknown property is read from within your script
7 __set( ) method is called whenever an undefined property is set in your scripts
8 __sleep() method is called by serialize() before it packs up the object
9 __toString( ) set a string value for the object that will be used if the object is ever used as a string
10 __wakeup() is called by unserialize()
