Is there any way to get similar functionality of the "diff" command (*nix) in PHP without having the performance hit of dropping to a shell?
This is going to be used for a web-based programming document system, kinda like CVS but with a focus on education rather than version preservation.
I've seen array_diff, and it looks pretty brain-dead and not what I need at all.
Your help would be VERY HIGHLY APPRECIATED!
