In PHP, how do I sort objects with built-in functions?

In PHP, you can sort objects using built-in functions like `usort()`, `uasort()`, and `uksort()`. These functions allow you to define a custom comparison function to sort the objects based on specific properties.

    usort($people, function($a, $b) {
