So the big project that I've been working on uses Sajax which is a library that makes the whole AJAX->PHP thing easier. The thing is, it doesn't make it that much easier and it doesn't do a few things that I'd like it to do. Its development seems to have stagnated as well.

So I'm on the casual lookout for a replacement before the big re-factor that we're about to take on. I came across SAJA because I track the Freshmeat RSS feed. I started reading the documentation and found this:

Once the class is initialized, you must specify the path to saja. (relative URL to the directory which contains the 4 files, with leading and trailing slash) $saja->set_path('/saja/');

I don't mean to pick on the SAJA library specifically, it just happened to be the catalyst for this rant. It could have been any of the thousands of stupid PHP applications that require this sort of nonsense.

Your PHP library/app should never need to know where it lives in the filesystem or relative to the web root or what your domain name is! Never ever ever never.

If I can write this (complete with breadcrumbs, rss/atom feeds, and livesearch) and the code doesn't need to know any of that stuff, your code doesn't need to either.

Please fix your code!
