What are some best practices for using array_chunk and shuffle functions in PHP for randomizing items?

When you need to randomize items in an array in PHP, you can use the `shuffle` function to randomly shuffle the elements of the array. If you also want to divide the array into chunks after shuffling, you can use the `array_chunk` function to split the shuffled array into smaller arrays. 

// Original array with items
$items = array("Item 1", "Item 2", "Item 3", "Item 4", "Item 5");

// Shuffle the items in the array
shuffle($items);

// Divide the shuffled array into chunks of 2 items each
$chunks = array_chunk($items, 2);

// Output the chunks
foreach ($chunks as $chunk) {
    echo implode(", ", $chunk) . "<br>";
}
