How can a Closure in PHP access a class constant?

Closures in PHP can access class constants by using the `use` keyword to import the class name and then accessing the constant within the closure. This allows the closure to access the class constant as if it were a variable within its scope. 

class MyClass {
    const MY_CONSTANT = 'Hello';

    public function myClosure() {
        $closure = function() {
            echo MyClass::MY_CONSTANT;
        };

        $closure();
    }
}

$myClass = new MyClass();
$myClass->myClosure(); // Output: Hello
