I need an explanation of a wrapper class with an example that a child would understand
<p>I read <a href="http://stackoverflow.com/questions/889160/what-is-a-wrapper-class">this entire post</a>.  It describes what a wrapper class is to other experienced programmers, but not to a newbie like me. </p>

<p>I understand PHP syntax, the object-oriented concept, but have not written my own application in object-oriented code yet. I am beyond confused when trying to figure out what exactly a wrapper class is. I don't understand the technical jargon. </p>

<p>I hope someone answers with a beautiful detailed child-like description that is easy to understand for someone that understands the basics of object oriented program and has read through pretty much the entire php.net language reference, but has no actual object oriented programming experience. No applications written yet. </p>
