php Closure object how to read it?

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 ...

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.

try print_r it will print array or object

print_r($my_var);
