RE: [PHP] vars

I agree with this completely. You have to make the code self-documenting in some way, otherwise you are going to be spending all your time trying to figure out what the heck you did last month. Good variable names go a lot further than good comments in this direction. Since PHP is an interpreted language it is going to cost a little bit, but keep in mind that this does NOT go out to the net, which is probably your bottleneck. By the way, I LOVED that satiric example from Ed Vul. It didn't answer your question, but it did point out the extremes of bad variable names. > From: David Newcomb [mailto:davidn@vnvi.com] > > Kurth, > > In any parsed tranlated language there is a penality cost for using long > token names.
