title: PHP competency test?
body: <p>Are there any good free PHP competency tests out there? It's easy for someone to say they code in PHP, but depth and understanding of how lowerlevel parts of the language are parsed and executed is much different.</p>
  
  <p>Something that asks good questions, perhaps elicit the person to write some sample code solutions to particular problems.</p>
  
  <p>Ideas?</p>
