Since PHP 8.1, a nullary ellipsis may be used to create a [[closure (computer programming)|closure]] from a callable or an object method:<ref>{{Cite web |title=PHP 8.1.0 Release Announcement |url=https://www.php.net/releases/8.1/en.php#first_class_callable_syntax |access-date=2023-03-29 |website=php.net}}</ref>

<syntaxhighlight lang="php">

// old style: PHP 8.0 and older

$foo = [$this, 'foo'];

$fn = Closure::fromCallable('strlen');

// new style: PHP 8.1 and newer

$foo = $this->foo(...);

$fn = strlen(...);
