How can PHP arrays be shuffled randomly?

To shuffle PHP arrays randomly, you can use the `shuffle()` function provided by PHP. This function shuffles the elements of an array in a random order. By calling `shuffle()` on the array you want to shuffle, you can easily randomize the order of its elements.

$myArray = [1, 2, 3, 4, 5];
shuffle($myArray);
print_r($myArray);
