class hierarchy design - order of classes
<p>What is the best way to order a a group of classes.  I've already made the decision to put them in one file.  An opcode caching application well ensure efficiency.</p>

<p>Is alphabetical O.K? Does it matter?  Here is the list.</p>

<pre><code>/*CLASS LIST*/

  /*bookmark*/
  /*database*/
  /*import*/
  /*one_db*/
  /*post*/
  /*route*/
  /*session*/
  /*signup*/
  /*table_maintain*/
  /*tweet*/
  /*upload*/
  /*validate*/
  /*view_html*/
</code></pre>
