What potential pitfalls should be considered when using the end() function in PHP?

When using the end() function in PHP, one potential pitfall to consider is that it moves the internal pointer of the array to the last element, which can affect the behavior of other array functions. To avoid unintended consequences, it's important to reset the array pointer using reset() after using end(). This ensures that subsequent array functions operate as expected.

$array = [1, 2, 3, 4, 5];
$lastElement = end($array);
reset($array); // Resetting the array pointer
