How can PHP developers ensure that object sorting functions are efficient and maintainable in their code?

To ensure that object sorting functions are efficient and maintainable in PHP code, developers can use the usort() function along with a custom comparison function. By defining a separate comparison function, developers can easily modify the sorting logic without cluttering the main codebase. Additionally, using the usort() function allows for efficient sorting of objects based on specific criteria. 

class User {
    public $name;
    public $age;
    
    public function __construct($name, $age) {
        $this->name = $name;
        $this->age = $age;
    }
}

$users = [
    new User('Alice', 25),
    new User('Bob', 30),
    new User('Charlie', 20)
];

// Custom comparison function for sorting users by age
function compareUsersByAge($a, $b) {
    return $a->age - $b->age;
}

usort($users, 'compareUsersByAge');

foreach ($users as $user) {
    echo $user->name . ' - ' . $user->age . PHP_EOL;
}
