PHP and Apache-style htpasswd files

Does PHP provide functions to deal with Apache-style htpasswd files? I mean, it's not like it's difficult to just parse it myself (explode() seems obvious enough), but it seems like that's something that would be built in to PHP.

Nothing built in, but there is a class file I use on the empeg logo site. Let me dig it up...

Ahh, here it is, it's from the PHP3 days, but still works fine. http://www.thewebmasters.net/php/Htpasswd.phtml

Since I don't need to manipulate the file, but just read it, I think I'll stick with just dealing with it manually if there's no built-in function. Thanks for confirming the non-existence, though.
