title: create a portal with php and joomla
body: <p>I am new in <code>php</code> and <code>joomla</code> and for now, studying book "<code>Sams Teach Yourself PHP in 24 hour</code>".</p>
  
  <p>I want to create an portal with PHP (and <code>Joomla</code>) that certain people with definite level of access can input data or use data...</p>
  
  <p>Please tell me how should I do this? I must start from what and where?</p>
  
  <p>Is reading <code>PHP</code> and be familiar with <code>Joomla</code> is enough?</p>
