For all those who were asking I'll try to throw together a deb that has lighttpd along with PHP 5 prebuilt and ready to go in the next day or two when I get some time. I don't remember which modules specifically I had compiled when I initially did my build, but I'll double check and post up a link to the deb along with some instructions (though it should be pretty straight forward...).

As qole pointed out there's a full Apache build in the repos, but in my experience if you're just interested in serving up PHP content for your own local use Apache is massive overkill, but that's just my oppinion ;o)

Thanks,
