What is Class !: (PHP year 2006 )
Let us summarize how to define a class, properties, methods, scope as public or private.
- Private : Public : private variables/functions can be used within the class;
- A public function can relay the variable outside the class.
- The line //print("$members->pwd<br>\n"); would throw an error. (<-click this link)
