Tobias Schlitt mentions today in his latest post about his first patch to PHP, an update to the pathinfo function's code being commited.

Hehe, some might say, that those 10 lines of C code are not even worth calling it a patch. Especially, since it was mostly copy and paste work and since Christian Schneider also adviced me for some improvement. Anyway, Marcus just commited my enhancement to pathinfo(), which adds a new field "filename" to the returned array of path elements.

His patch adds a much needed output parameter to the pathinfo function's results - filename. He talks briefly about the process of making the change and how long it took him on the first shot (2 hours), but now his hard work has paid off. The update will be a part of PHP 5.2.
