What is the disadvantage of using PHP?
As far as I know.. the only bad issue I see as a PHP developer is that you don't have the variables/attributes type. I mean you can set an integer attribute then set the same attribute as string. And I just discovered that if you use a non-static method as static, the php accepts it as if it was normal... =P The advantage of using php is that you may develop your systems faster and easily.

Can a static method access instance variables?
Variables cannot access variables; only methods can access variables. Non-static methods (also known as instance methods) are local to an object of the class and therefore have access to a "this" reference (referring to the current instance of the class, the object upon which the method was invoked), but static variables are local to the class itself. These variables are shared by all objects of the class and are therefore accessible to non-static methods. Static variable are also accessible to static methods and are therefore accessible even when no objects of the class exist.
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
