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 ...

Answer 1

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

$myvar();

Since php5.4 with Array Access:

 echo   $myvar()[0];
