In what scenarios would using array_multisort be more advantageous than usort for sorting multidimensional arrays in PHP?
When sorting multidimensional arrays in PHP, using array_multisort can be more advantageous than usort when you need to sort multiple columns or keys within the array. Array_multisort allows you to sort multiple arrays or multidimensional arrays based on one or more criteria, while usort is more suitable for sorting a single array based on a custom comparison function.
// Sample multidimensional array
$users = [
['name' => 'John', 'age' => 30],
['name' => 'Alice', 'age' => 25],
['name' => 'Bob', 'age' => 35]
];
// Sorting the array by name in ascending order
array_multisort(array_column($users, 'name'), SORT_ASC, $users);
// Output the sorted array
print_r($users);
