Are there any best practices for handling and manipulating shuffled arrays in PHP?

When working with shuffled arrays in PHP, it is important to maintain the integrity of the original array while manipulating the shuffled version. One common approach is to store a copy of the original array before shuffling it, so that the original order can be restored if needed. Additionally, using array functions such as array_map or array_filter can help in manipulating shuffled arrays without affecting the original data.

// Create a copy of the original array before shuffling
$originalArray = $shuffledArray;

// Manipulate the shuffled array without affecting the original data
$shuffledArray = array_map(function($item) {
    return $item * 2;
}, $shuffledArray);

// Restore the original order if needed
$shuffledArray = $originalArray;
