When you import the symbols, just provide the full path from the repository root, even if you're only importing a subpath (in this case, just put "/trunk/" in front of everything).

Possibly we could infer the subpath, but this seems like a pretty easy fix. I'll mention it in the documentation, though, since I agree it's a bit confusing.

Let me know if that doesn't work.

thanks!

i reset the symbols index by prefix '/trunk' in the file path.

and it work fine.

and, i have a proposal.

the php syntax symbols link domain to custom, because i install this project in Internal network。

On the other part, you basically just mean you want a config option to replace php.net with phpdocs.yourinstall.secretnetwork.com?
