How to reverse the order of elements in an array in PHP?

One way to reverse the order of elements in an array in PHP is by using the array_reverse() function. Here's an example:

$array = [1, 2, 3, 4, 5];
$reversedArray = array_reverse($array);

print_r($reversedArray);

The output will be:

Array
(
    [0] => 5
    [1] => 4
    [2] => 3
    [3] => 2
    [4] => 1
)

Alternatively, you can use the array_reverse() function with the second parameter true to preserve the keys of the original array:

$array = [1 => 'a', 2 => 'b', 3 => 'c'];
$reversedArray = array_reverse($array, true);

print_r($reversedArray);

The output will be:

Array
(
    [3] => c
    [2] => b
    [1] => a
)

Note that the original array is not modified, and a new array with reversed elements is returned.
