Functions WebDev/*nix assorted functions & hacks

Greetings!

What you see here is a growing collection of functions/stuff I've collected and created over the years.
I've put them online so they're at hand wherever I do PHP stuffs, and to have a place that will always have the latest versions of them (theoretically).
You can redistribute and/or modify most (some are not mine) functions and source code offered here under the terms of the GNU
General Public License, available at gnu.org/licenses.
If I didn't write it, it should mention a source url.

Then, there's non-PHP stuff like TextMate commands, Linux tricks & URLs, mod-rewrite & regex, some ancient shellscripts (don't use),
Firefox config settings, OS X tricks, etc etc..

This being the first re-write, I added some shortcuts: j/k for next/previous function in the (found) list, f(ind) to jump to the search box.
When clicking a category, it should still be focused after the page load for easier kb navigation.
In the URL, replacing the id by qs prints just the function in plaintext, like this: funcs.php?qs=264.
