Closures can be either anonymous or not.

Here is an anonymous closure:
$c1 = function () {};

And here is a *non* anonymous closure:
$c2 = Closure::fromCallable(['Foo', 'bar']);

ReflectionFunction::isAnonymous() returns true for $c1 and false for $c2.

Before PHP 8.2, one had to do this check to decide between both:
$r = new \ReflectionFunction($c1);
$isAnonymous = false !== strpos($r->name, '{closure}');

ReflectionFunction::isAnonymous() makes it easier to check.

You know that anonymous function is just an instance of class `Closure` so this would be equivalent to check whether a variable is an anonymous function or not:

<?php

$test
= function () {};

if (
is_callable($test) && is_object($test) && $test instanceof Closure) { /* ... */ }

?>
