php Closure object how to read it?

Question

I have this code but I am stuck...

$my_var = function (){ return array('hello you'); }; var_dump($my_var); // returns object(Closure)#2 (0) { }

how do I echo $my_var?

I would assume it would be echo $my_var[0]; but this does not work.

Fatal error: Cannot use object of type Closure as array in ...

Someone at PHP headquarters should be keelhauled for that error message. It demonstrates a dramatic lack of understanding of closure. — Beetroot-Beetroot

A closure is a function. Therefore you have to call it, like this :

$myvar();

Since php5.4 with Array Access:

 echo $myvar()[0];

$my_var represents a function. You need to call it first to get the return value.
