How do you test code that uses heap vs stack?

Testing code that utilizes both heap and stack memory is essential for understanding memory management in programming. Heap memory is used for dynamic memory allocation, while stack memory is used for static memory allocation. Here is an example demonstrating the difference between the two.


        <?php
        function stackExample() {
            $a = 10; // stack allocation
            $b = 20; // stack allocation
            return $a + $b;
        }

        function heapExample() {
            $arr = array(); // dynamic allocation (heap)
            for ($i = 0; $i < 5; $i++) {
                $arr[$i] = $i * 10;
            }
            return $arr;
        }

        // Testing stack memory usage
        echo "Stack sum: " . stackExample() . "<br>";
        
        // Testing heap memory usage
        echo "Heap array: ";
        print_r(heapExample());
        ?>
