Are there any best practices for efficiently sorting data by multiple columns in PHP?

When sorting data by multiple columns in PHP, a common approach is to use the `array_multisort()` function. This function allows you to sort an array by multiple columns in a single call, making the sorting process more efficient. By passing the array to be sorted along with the columns to sort by, you can easily achieve the desired sorting order. 

// Sample data to be sorted
$data = [
    ['name' => 'John', 'age' => 30, 'city' => 'New York'],
    ['name' => 'Alice', 'age' => 25, 'city' => 'Los Angeles'],
    ['name' => 'Bob', 'age' => 35, 'city' => 'Chicago'],
];

// Sort data by 'age' column in descending order, then by 'name' column in ascending order
array_multisort(array_column($data, 'age'), SORT_DESC, array_column($data, 'name'), SORT_ASC, $data);

// Output sorted data
print_r($data);
