I've been looking for a source code browser that makes it easy to look up definitions of functions. I use that function in Netbeans a lot and I was wondering if there is no software that could provide such a function outside of an IDE. Well, there certainly is such a solution and it is nearly antique. It is called PHPXref and I have used it on the source code of Vanilla 220.127.116.11. You can access it here: http://vnxref.bplaced.net
I'll upload the source for 2.1b2 in the next 24hours, I think. Maybe you find it as useful as I do.
