i'm on PHP training and our lector is telling us that to avoid

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.
