Sorting an array of objects by one property in PHP

Hello everyone! I'm a beginner in PHP and I've encountered a problem when sorting an array of objects. I have an array that contains objects of the `User` class. Each object has properties `name`, `age`, and `score`. I need to sort this array by the `age` property in ascending order, but I can't figure out how to do it correctly. Here's an example of my code: ```php class User { public $name; public $age; public $score; public function __construct($name, $age, $score) { $this->name = $name; $this->age = $age; $this->score = $score; } } $users = [ new User('Alice', 25, 90), new User('Bob', 30, 85), new User('Charlie', 22, 95), new User('Diana', 28, 88) ]; // Trying to sort, but I don't know which function
