PHP Get value from config array

I have a config.php file that looks like this

return array(
"array1"=>
    array(
      "array2"=>"value"
    )
);

How can I dynamically extract array2 value using a function like this?

function getConfigValue(?)
{
    $config = include("config.php");
    return $config....  
}

Solution 1

$path  = 'array1.array2';
$value = array_reduce(
    explode('.', $path),
    function (array $value, $key) { return $value[$key]; },
    $config
);

Note: Use and implement solution 1 because this method fully tested our system.
