title: Eclipse autocomplete is not working for PHP-project
body: <p>My Eclipse doesn't use auto-complete... My colleague get a whole list of suggestions by just typing some letters and I get nothing...</p>
  
  <p>The Eclipse version I use is: </p>
  
  <pre><code>Eclipse for PHP Developers
  
  Version: Helios Service Release 2
  Build id: 20110301-1815

  <p>And I think I've set all available settings for autocomplete.<br>
  I lose a huge amount of time every time I have to search for the correct naming. Is there any module of software I've to install extra to get this autocompletion? </p>
