Eclipse autocomplete is not working for PHP-project

Question

My Eclipse doesn\'t use auto-complete... My colleague get a whole list of suggestions by just typing some letters and I get nothing...

The Eclipse version I use is:

Answer 1

I can try ALL answers (from this and others threads), only work for me delete (or rename for backup) .metadata folder on workspace folder

1. Close eclipse
2. mv .metadata .metadata_older
3. Start eclipse (clean start wrokspace of eclipse, none project are listed)
4. Import from workspace your project
5. Eclipse rebuild and refresh works (several project settings are lost!!!)
6. Autocompletion, follow code, etc now work.

This isn't the ideal solution, but is the ONLY solution for me, I migrated from eclipse 3.6 to 4.4 in one step, and PHP support is gone, only highlight code are working until delete .metadata folder.
