It would be a bad idea to create a function list to reference pages in the manual, since there are a lot of functions not (yet) documented, but listed in the funcsummary file.
Well, so I just add the functions that are only found in that file to the list and everything would be fine, won't it?
It contains functions that should not be used.
I would suggest you look into the XSLT sheet published by the PHPEdit guys, which generates a reference list
in XML format out of the PHP manual.
I did that and don't like it to much since it processes the whole manual. (everything has to be downloaded and it takes quite a while to run on my old box..)
You don't need to do it every hour. It is better to have correct data, then having data fast.
Just one more question: how often are that files updated?
Those are human-updated.
