Answer 1

There seem to still be a lot of bugs related to auto-completion for the PHP Development Tools Project (PDT) (See Open Bugs).

One has been entered two days ago: bug 286733 "When using sub namespace completion does not work."

But this is hardly the only one:

• "Autocomplete on namespaces failed" (bug 281766)
• "[php 5.3] Code assist doesn't provide method completion" (bug 286068)
• ...

They are all related to the namespace of the PHP code. Could you check if you reproduce the error in a global namespace?

Answer 2

As noted before the 'natures' node for php core is listed but this is most insufficient when the project is imported or checked out.

• Make a backup of your .project
• Remove the 'natures' node children
• Close/Re-open eclipse
• Right-click project -> Configure -> Add PHP Support
• Add back other 'natures' children

The issue is that project will not make the necessary imports because it assumes it already has.
