What is the purpose of sorting the array multiple times in PHP?

When sorting an array multiple times in PHP, it may be necessary to ensure that the array is sorted in a specific way or to apply different sorting algorithms for different use cases. This can be achieved by calling the sorting functions multiple times with different parameters or conditions.

// Example of sorting an array multiple times in PHP

$array = [5, 2, 8, 1, 9];

// Sort the array in ascending order
sort($array);

// Sort the array in descending order
rsort($array);

// Sort the array in natural order
natsort($array);

print_r($array);
