title: Advices on creating a first e-Commerce application?
body: <p>I need to create a e-commerce application in PHP.
  As a first option I though to use Magento, that I already used one or two times in the past.
  But as the requirements are growing, I think Magento is not correct choice, there are too much options I don't need, and some options which are not available and/or some customization which will be difficult.</p>
  
  <p>So I think I'll write it from the scratch using Zend Framework which I'm used too.</p>
  
  <p>Do you have any advices to start ?</p>
  
  <p>I think for example about :</p>
  
  <ul>
  <li>Session storing (filesystem &lt;-> db) ?</li>
  <li>Payment module security (Paypal, CB, and checks)</li>
  <li>Computation with SQL Stored Procedures ?</li>
  </ul>
  
  <p>What is yours ?</p>
