What are the potential pitfalls of using array_multisort for sorting multidimensional arrays?

One potential pitfall of using array_multisort for sorting multidimensional arrays is that it can be complex to use and understand, especially for beginners. Additionally, array_multisort modifies the original array directly, which can lead to unexpected results if not handled carefully. To avoid these pitfalls, consider using a custom sorting function with usort instead, which provides more control and clarity in sorting multidimensional arrays. 

// Sample multidimensional array
$students = array(
    array('name' => 'Alice', 'age' => 20),
    array('name' => 'Bob', 'age' => 22),
    array('name' => 'Charlie', 'age' => 18)
);

// Custom sorting function based on 'age'
usort($students, function($a, $b) {
    return $a['age'] - $b['age'];
});

// Print sorted array
print_r($students);
