What are some best practices for sorting multidimensional arrays efficiently in PHP?

When sorting multidimensional arrays efficiently in PHP, it is important to use the array_multisort() function along with array_column() to sort the array based on a specific column. This allows for sorting on multiple levels of the array without having to write complex sorting algorithms. 

// Sample multidimensional array
$users = [
    ['id' => 1, 'name' => 'Alice', 'age' => 30],
    ['id' => 2, 'name' => 'Bob', 'age' => 25],
    ['id' => 3, 'name' => 'Charlie', 'age' => 35],
];

// Sort the array by 'age' column in ascending order
array_multisort(array_column($users, 'age'), SORT_ASC, $users);

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