Declaring an anonymous function within new stdClass
PHP is right when invoke fatal error Call to undefined method stdClass::city() because object $class->address('name') has no method city.Intead, this object has property city which is instance of Closure Class (http://www.php.net/manual/en/class.closure.php)You can verify this: var_dump($class->address('name')->city)
I found the way to call this anonymous function is:
$closure = $class->address('name')->city;$closure('class');Hope this helps!
Sadly it is not possible within stdClass, but there is a workaround -- PHP Anonymous Object.
// define by passing in constructor$anonim_obj = new AnObj(array( "foo" => function() { echo "foo"; }, "bar" => function($bar) { echo $bar; } ));$anonim_obj->foo(); // prints "foo"$anonim_obj->bar("hello, world"); // prints "hello, world"
AFAIK, this is not supported by PHP, and you must use the call_user_func() or call_user_func_array() functions to call closures assigned to class properties (usually you can use __call() to do this, but in your case, the class is stdClass, so this isn't possible).
