Does cscope support PHP?
I don't think so. Exuberant tags suppose a lot of languages but it
does not do references (I think) -- just definitions.
Thanks for the link

At least once a week, I want to find some code that uses a few

wait
for it to finish.
I wonder if I could store our source code in a postgresql table and
then use full text searching to index. Then I hope I could run a
query
where I ask for all files that use modules X, Y, and Z.
DBMSs are great tools for the right job, but IMO this is not the
right job. I can't see how a database engine, with all it's
transactional overhead and many other layers, will ever beat a
simple grep performance-wise. I've used Eclipse for refactoring,
but having done it once, I'm sticking with grep.
This is exactly what cscope is good for.

I've used it since the early 90's. I do level 3 support for really
big companies. If you are an emacs fan, its hooked in to it as well.
You want to use the -q option. If it is a million lines of code, its
going to take a while. It pseudo-parses the code (some tricky
constructs will confuse it) and builds a very simple database file.
I think it uses Berkeley's DB file. After that, finding all the
occurrences of foo is a few seconds.
If you want to find just definitions (like where is foo defined),
then use ctags or etags. There is exuberant ctags here:
