While fuzzeling around with iterators (trying to find the next and previous item in a list), discovered something odd: <?php for($i=0; $i < $max; $i++ && print 'increment,') { do_something(); echo " i = $i\n"; } echo "finally, i = $i\n"; ?> If $max is set at 1 (only the first run will occur), it works as I expected: i = 0 finally, i = 0 But with $max at a higher value (say 2) it works different: i = 0 increment, i = 1 increment, finally, i = 2 After the loop was finished $i was incremented! As I read right now, this is what should happen. But it doesn't occur in the first case. As I said, I was searching something using an iterator, and after the loop I wanted to know the next value. Because of this 'feature' (a.k.a. bug) that didn't work.
