Answer 1

Add your own error handling in case the key path isn't in your array, but something like:

$array = array('data' => array('one' => 'first', 'two' => 'second'));

$key = 'data.one';

function find($key, $array) {
    $parts = explode('.', $key);
    foreach ($parts as $part) {
        $array = $array[$part];
    }
    return $array;
}

$result = find($key, $array);
var_dump($result);
