How to deal with a multidimensional two-dimensional array?

Question

PHP

I get an array of data

$array = array();

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://shikimori.org/api/animes/27833/screenshots');
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "User Agent");
    if ($content = curl_exec($ch)) {
      $array = json_decode($content, true);
    }
    curl_close($ch);

The array comes in the form:
