Are there any specific best practices to follow when sorting objects in PHP?

When sorting objects in PHP, it is important to implement a custom comparison function that defines the sorting criteria. This can be achieved by using the usort() function, which allows you to specify a user-defined comparison function to sort the objects based on specific properties or values. 

class MyClass {
    public $name;
    public $age;

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

$objects = [
    new MyClass('John', 30),
    new MyClass('Alice', 25),
    new MyClass('Bob', 35)
];

usort($objects, function($a, $b) {
    return $a->age <=> $b->age; // Sort objects based on age in ascending order
});

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