Re: declaring variables in class definitions

You should define a structure of the class before using the class. You can set the value of the $somevar anytime later, when using an object of class a. $d->somevar = true; and the next call to $d->b() will print nothing. But you won't be able to assign a value to $somevar, if it is not declared in the class. sic> Maybe a better question is what will break if I do not declare sic> my vars in my class definition? the method b() of the class a will break if you don't declare $somevar in the class definition. In the string "if (!isset($this->somevar))" it would throw an error saying that you have no variable named 'somevar' in you class. -- Best regards, Max A.
