$uri = $_SERVER['REQUEST_URI'];
$exploded = explode('/', $uri);
$array = array_values(array_filter($exploded));
$route = [];
$index = 0;
foreach ($array as $item) { $route[$index] = [ 'route' => $index, 'translation' => ($index === 0) ? $index : $route[$index]['translation'] . '.' . $index ]; $index++; } return $route;`

For some reason, this code results in wrong pointer to the 'unexisting' array element. I have 3 elements in the main array i'm working with, starting counting from 0 and should finish on 2. But due to some unknown power, after setting first element in the new array, second one throws undefined offset error. Can someone tell me how PHP code is processed in the layout code block?
