What are the potential pitfalls of using the shuffle function in PHP for randomizing data?

One potential pitfall of using the shuffle function in PHP for randomizing data is that it modifies the original array in place, which may not be desired if you need to keep the original order intact. To solve this issue, you can create a copy of the original array before shuffling it.

// Create a copy of the original array
$originalArray = [1, 2, 3, 4, 5];
$shuffledArray = $originalArray;

// Shuffle the copied array
shuffle($shuffledArray);

// Output the shuffled array
print_r($shuffledArray);
