What is the difference between using array_pop and end function to access the last element of an array in PHP?

The main difference between using array_pop and end functions to access the last element of an array in PHP is that array_pop not only returns the last element but also removes it from the array, while end simply returns the last element without modifying the array. If you only need to retrieve the last element without altering the original array, you should use the end function. If you want to retrieve and remove the last element from the array, array_pop is the appropriate choice.

// Using end function to access the last element of an array
$myArray = [1, 2, 3, 4, 5];
$lastElement = end($myArray);
echo $lastElement; // Output: 5
print_r($myArray); // Output: [1, 2, 3, 4, 5]

// Using array_pop function to access and remove the last element of an array
$myArray = [1, 2, 3, 4, 5];
$lastElement = array_pop($myArray);
echo $lastElement; // Output: 5
print_r($myArray); // Output: [1, 2, 3, 4]
