Are there any specific considerations to keep in mind when sorting data by multiple columns in PHP for optimal performance?

When sorting data by multiple columns in PHP, it is important to consider the efficiency of the sorting algorithm used. One way to optimize performance is to use a stable sorting algorithm like mergesort or quicksort. Additionally, you can use array_multisort() function in PHP to sort an array by multiple columns efficiently. 

// Sample data array
$data = [
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 30],
    ['name' => 'Alice', 'age' => 20],
];

// Sort the data array by 'name' and then 'age'
array_multisort(array_column($data, 'name'), SORT_ASC, array_column($data, 'age'), SORT_ASC, $data);

// Output the sorted data
print_r($data);
