get KEY & VALUE from array in PHP?

Question

You can easily get an key from a array but if I have the value, and I have the key,In array And wants boths, whats the best way to get it?

like :

$controller = $request->get('_controller');
$home     = array('XXX\ABCBundle\Controller\PageHomeController::indexAction'=>5, 'XXX\ABCBundle\Controller\RegistrationController::confirmedAction'=>10);

First time I want key for compression and when this is inter then want to key:-

if(in_array($controller,$home)){
       echo "blabla";
   $point = $home[$controller];

}

But this is not working.

in_array searches for a value, but you're looking for a key. You should use array_key_exists for this, or isset($home[$controller]).

if (isset($home[$controller])) {
    echo "blablah";
    $point = $home[$controller];
}
