PDT autocomplete broken in Eclpise

Question

Suddenly I can't use autocomplete in my Eclipse PHP projects. When I press alt+/ I jsut hear a dummy sound. Which settings should I check?

Answer 1

Does you PHP Language Library include a link to your local PHP install? Sometimes I've found my project gets corrupted, and that PHP gets stripped from that include.

Answer 2

In this situation, simply reloading Eclipse helped.

Answer 3

Try this. Right-click your top level folder in PHP Explorer. Select the "Configure" menu item then "Add PHP Support".
