[Phpgroupware-developers] i++ versus ++i

[Kai Hofmann]

Just for info, why it is better to use ++$i instead of $i++

source: http://www.gotw.ca/gotw/002.htm

Preincrement is more efficient than postincrement, because for postincrement
the object must increment itself and then return a temporary containing its
old value. Note that this is true even for builtins like int!

[Guideline] Prefer preincrement, avoid postincrement.



Have a happy weekend.
