How can I create a class in PHP? Example code:

class Person {
    public $name;
    public $age;

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

    function get_name() {
        return $this->name;
    }

    function get_age() {
        return $this->age;
    }
}

// Create a new Person object
$person = new Person("John Doe", 30);

// Call methods on the Person object
echo "Name: " . $person->get_name() . "<br>";
echo "Age: " . $person->get_age();
