How can PHP developers ensure that a top ten list script sorts in the correct order?

When creating a top ten list script in PHP, developers can ensure that the list sorts in the correct order by using the `usort` function with a custom comparison function. This function should compare the values based on the desired criteria, such as numerical value or alphabetical order, to correctly sort the list.

// Sample array of top ten items
$topTenList = array(
    "Item 1" => 10,
    "Item 2" => 8,
    "Item 3" => 5,
    "Item 4" => 9,
    "Item 5" => 3,
    "Item 6" => 7,
    "Item 7" => 2,
    "Item 8" => 6,
    "Item 9" => 4,
    "Item 10" => 1
);

// Custom comparison function to sort the list in descending order
usort($topTenList, function($a, $b) {
    return $b <=> $a;
});

// Output the sorted top ten list
foreach($topTenList as $item => $rank) {
    echo $item . ": " . $rank . "\n";
}
