File I/O on large files is near impossible with PHP.  File() eats way too much ram, and is slow, and the fopen() method is slow and hard to seek to a line where you left off processing at. Perhaps including functions that allow reading a given line of a file, checking the total number of lines, and more speed/ram aware I/O functions to allow processing of log files, and other large files.

I'm not a c coder, but I'm more than willing to help in any way I can.

Thanks and keep up the good work.
