Echo array_values from array

I am very new in PHP and I was checking whether all my controlers are in so how can I echo this? what I tried resulting nothing 

 $controllers = array_intersect($json_api->get_controllers(), $active_controllers );

  $return = array(
    'json_api_version' => $version,
    'controllers' => array_values($controllers)
  );
echo $return['controllers']['controllers'];

If you want to print the values of an array with a understandable format you should use print_r() instead of echo like so: 

print_r($return['controllers']);

You can also use var_dump() to get some extra information about the fields, like the type and lenght.

If what you need is to asign a certain index of the array to a value just do something like this: 

$variable = $return['controllers'][indexOfField]; // indexOfField=2 for city field
echo $variable;

For further information about print_r() check the official manual.

use print_r function:

print_r($return['controllers']);

when you want read city you do:

$arr_controllers = $return['controllers'];
$key_2 = $arr_controllers[2];

where 2 is the key
