i'm on PHP training and our lector is telling us that to avoid counting anarray item amout thanks count($my_array), he tells we can do: while($my_array) { ... do something } but from experience this is an infinity loop...it should be always something like $count = count($my_array); while($i <= $count) { ... do something ... $i++; } has someone already use such syntax ? i mean as the first one.
The while would work if you removed elements of $my_array inside the loop, but you would still need to be sure that it would eventually be empty.
I would guess that your lecturers point is that you shouldn't call count on every iteration as it's a waste of time. He may also be confusing while for foreach in which case I'd leave because you're unlikely to learn anything from him.
