What are the advantages of using built-in PHP functions like array_multisort for sorting multiarrays compared to custom functions?

When sorting multiarrays in PHP, using built-in functions like array_multisort is advantageous because they are optimized for performance and reliability. These functions are well-tested and widely used, ensuring that the sorting process is efficient and accurate. Additionally, built-in functions often come with additional features and options that make sorting complex multiarrays easier and more flexible compared to writing custom sorting functions from scratch.

// Sample multiarray to be sorted
$multiarray = array(
    array("name" => "John", "age" => 30),
    array("name" => "Alice", "age" => 25),
    array("name" => "Bob", "age" => 35)
);

// Sorting the multiarray by 'name' in ascending order
array_multisort(array_column($multiarray, 'name'), SORT_ASC, $multiarray);

// Displaying the sorted multiarray
print_r($multiarray);
