What are the potential pitfalls of using natsort with arrays in PHP?

When using natsort with arrays in PHP, one potential pitfall is that it will modify the original array rather than returning a sorted copy. This can lead to unexpected behavior if the original array needs to be preserved. To solve this issue, you can make a copy of the array before sorting it with natsort. 

// Create a copy of the original array
$originalArray = [3, 20, 1, 10];
$sortedArray = $originalArray;

// Sort the copy using natsort
natsort($sortedArray);

// Output the sorted array
print_r($sortedArray);

// Original array remains unchanged
print_r($originalArray);
