Access array key value without specifying the key

Question

I have:

public $staticRoutes = array(
        'dog-toys' => 'Index',
        ) ;

if(array_key_exists($controller, $this->staticRoutes))
{
    $controller = new $controller ;
}

The new $controller is becoming 'dog-toys', which is not what I want.

How can I change what I have so that $controller = new Index ; ?

Some variation of:

$controller = new ${staticRoutes[$controller]} ;

I cannot test it right now, so to be safe you could also do:

$ctrl = $staticRoutes[$controller];
$controller = new $ctrl;

OP - This works because your array is what's known as an associative array. Your $controller variable is actually referencing the key of that array, so you can access the value the same way you would with an indexed (numbered) array - array[key].

You would need to actually use you $staticRoutes array like this:

$controller_instance = new $this->staticRoutes[$controller];

Note I changed the name of the variable you are assigning to for clarity's sake. I am also assuming that the code trying to instantiate this controller is in the same class (or inheriting class) where the $staticRoutes property is defined (thus the use of $this).
