PHP 5 is very very flexible in accessing member variables and member functions. These access methods maybe look unusual and unnecessary at first glance; but they are very useful sometimes; specially when you work with SimpleXML classes and objects. I have posted a similar comment in SimpleXML function reference section, but this one is more.

Some developers code their PHP projects writing classes of objects. Others also write classes but do it just because they see others doing it without being able to explain why classes are a good thing. Others do not write classes but reuse other people code written in the form of classes. Others completely refuse to write or reuse other developer classes because they do not see much point in.

Programmatically, a class is a code that is written to handle a specific task. This is your blueprint. You can build multiple houses from this blueprint, but, all of them will have the same properties (with different values) and the same methods. Let's see how to write a class in PHP. PHP Declaring Classes.
Class Friendship is a valuable expression for object modeling when used properly. It also has value in white-box testing as a tactical refactoring tool when approaching legacy applications.

I have a few classes that perform some MySQL queries and prepared statements. However, I am lost in how to incorporate my PDO object within those classes. For example, I want to do something like.
