"... should be obvious - but are often overlooked - points within coding practice that can cause the programmer to develop bad habits and bad code." - Dan Brown Tip #1: Don't use count() in loops unless there are very few items to count and performance doesn't matter, or the number will vary over the loop. That is, don't do this: for ($i = 0; $i < count($items); $i++) Instead, do this: $number = count($items); for ($i = 0; $i < $number; $i++)

Gah! for ($i=0;$i<sizeof($array);$i++) is something I do all the time. So the array size is being calculated each iteration?
