    say you have a customer who is buying something. The customer is checking 
    out, because he is done shopping. You have setup two pages, one with his 
    personal information such as name address etc. and the other with the 
    billing information. Since you are so organized and neat, you don't want 
    to jumble the page with form fields so you decided to have two separate 
    pages.</font></p>
   <p><font size="2" face="Arial, Helvetica, sans-serif">You think to yourself, 
    &quot;Wow, that's allot of variables to keep track of!&quot;. You ponder 
    how much work this will be and you finally come up with a solution: You 
    will use a class to store the information!</font></p>
   <p><font size="2" face="Arial, Helvetica, sans-serif">After designing and 
    building a class, you sit back and sip your beer. Unfortunately you cant 
    enjoy that sip because you realized that you have no idea how you are 
    going to send the information from page one over to page two!</font></p>
   <p><font size="2" face="Arial, Helvetica, sans-serif">Well, I'm going to 
    show you how to move your classes and your data that's held in them from 
    page to page.</font></p>

 <tr> 
  <td align="left" valign="top"><font size="2" face="Arial, Helvetica, sans-serif">Unfortunately, 
   due to my laziness, I gave a small, crude example. I think you get the point 
   though. Once you have designed and built your class, you can save it in 
   an include file. Make sure to have this file included in every .php file 
   you will be using your class in. In each page you will need to access your 
   class data by using <b><font size="1" face="Verdana, Arial, Helvetica, sans-serif">unserialize()</font></b> 
   and when you are finished you will need to save it again using <b><font size="1" face="Verdana, Arial, Helvetica, sans-serif">serialize()</font></b>. 
   I'm using the session method because I do not have access to write files 
   on my server, and it would be too hard to write a file for each person that 
   wants to order something. There are too many people. You can look in the 
   PHP manual (v10) to figure out how to write them to a file and retrieve 
   them from a file.</font></td>
