How do you find the end of a foreach loop?
Use count() to determine the total length of an array. The iteration of the counter was placed at the bottom of the foreach() loop – $x++; to execute the condition to get the first item. To get the last item, check if the $x is equal to the total length of the array. If true , then it gets the last item.
