I'll give you a simple case. I have a GTK PHP MP3 ID3 editor application I'm working on. When one opens a file in a directory, I provide next/prev buttons to quickly page to the next/prev file in the directory. Getting the next/prev to work is simple enough, but... I've got the whole array built from opendir/readdir, and sorted it into alphabetical order. I've got a filename inside that array, from the pre-defined GtkFileSelection dialog. So I need to initialize the internal array pointer to the position of the file within that array, there is no such PHP function.
