Bug Type: Documentation Problem
Bug description:Static anonymous functions are not documented
Description:
------------
---
From manual page: http://www.php.net/functions.anonymous
---
Since PHP 5.4 anonymous function can be declared statically
(https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#anonymous-function-creation).
When an anonymous function is declared statically, it prevents
auto-binding to the instance it is in. Also, it can not be bound using
the bind, bindTo & call functions.
Test script:
---------------
class Foo
{
public function bar()
{
return static function () {
var_dump($this);
};
}
public function baz()
{
return function () {
var_dump($this);
};
}
}
$foo = new Foo();
$bar = $foo->bar();
$bar();
// Notice: Undefined variable: this
// NULL
$baz = $foo->baz();
$baz();
// object(Foo)#1 (0) {
// }
Closure::bind($bar, new StdClass());
$bar->bindTo(new StdClass());
$bar->call(new StdClass());
// Warning: Cannot bind an instance to a static closure
