How can array_multisort() be utilized effectively in PHP for sorting arrays with multiple arguments?

When sorting arrays with multiple arguments in PHP, the array_multisort() function can be used effectively. This function allows you to sort multiple arrays or a multi-dimensional array based on one or more keys, providing a flexible way to sort complex data structures. 

// Example of using array_multisort() to sort a multi-dimensional array by multiple keys
$data = array(
    array('name' => 'John', 'age' => 30),
    array('name' => 'Jane', 'age' => 25),
    array('name' => 'Alice', 'age' => 35)
);

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

// Output sorted array
print_r($data);
