My PHP Loop is below

    foreach ($retr as $page) {
        echo $page['name'];
        //var_dump($page);
    }

Your array is multidimentional, being a single element array containing a further 19 child elements.

If you just want to itterate the child elements, then run the loop over the top level elelemt, not the parent array:

foreach ($retr[0] as $page) {...}
