The Closure class

    (PHP 5 >= 5.3.0, PHP 7, PHP 8)

    Introduction

    Class used to represent anonymous functions.

    Anonymous functions yield objects of this type. This class has methods that allow further control of the anonymous function after it has been created.

    Besides the methods listed here, this class also has an __invoke method. This is for consistency with other classes that implement calling magic, as this method is not used for calling the function.

    Class synopsis

    final class Closure {
    /* Methods */
    private __construct()
    public static bind(Closure $closure, ?object $newThis, object|string|null $newScope = "static"): ?Closure
    public bindTo(?object $newThis, object|string|null $newScope = "static"): ?Closure
    public call(object $newThis, mixed ...$args): mixed
    public static fromCallable(callable $callback): Closure
    }
