But since the value of $i is not tested in that statement, it makes no
difference.

It does in the sort of statement like while($i++<10); versus while(++$i<10)

I think. I NEVER EVER use an increment operator in a test statement
because if I can't remember, chances are the next person to read the
code wont, either.

Always ask yourself, 'how stupid, lazy & forgetful can I be on a Bad
Monday morning in February, double it, and assume the guy who has to
maintain your code is worse'

THEN when you come back to your code on that morning after a row with
your other half, ha raging hangover and you crashed the car on the way
in, you stand some chance of being able to find the bug as well;-)
