2,902 PointsWhen we use foreach loop to create $key=$item, how is $key storing numerical values and how are $item being initialised
So in the above video, we use foreach loop to display $key=$item, but the items are being initialised in next loop. Also, how is the value of $key is by default numerical that 0,1,2,3 when we have stored different keys in list.php
