How to get value of multiple values field in Drupal 8? - drupal-8

Question

I have multiple values image field in Drupal 8 and I would like to prepare values in Controller for output in the twig template.
It's simple (well, if we can call the ridiculously complicated "lets-do-everything-in-OOP-eventhough-its-useless" Drupal 8 way simple) for single value fields:
$nids = \Drupal::entityQuery('node')->condition('type', 'zbornik_a_foto')->execute();
$nodes = Node::loadMultiple($nids);
$data = array();
foreach ($nodes as $node) {
$data[] = array(
'rocnik' => $node->get('field_rok')->getValue(),
'miesto' => $node->get('field_miesto_konania')->getValue(),
'fotografie' => $node->get('field_zbornik')->getValue(),
'foto' => $node->get('field_fotografie')->getValue(),
);
}
return array(
'#theme' => 'riadky_zazili',
'#data' => $data,
'#title' => 'Zažili sme',
);
However, the field_fotografie value is multiple values field and I would like to get all image's URIs in the $data array. Does anybody know how? Ideally less than 10 lines of useless OOP jibber-jabber. Thanks.

Try like this way, it might be useful for you.
$data = array();
foreach($nodes as $node) {
$photo = array();
foreach($node->get('field_image')->getValue() as $file){
$fid = $file['target_id']; // get file fid;
$photo[] = \Drupal\file\Entity\File::load($fid)->getFileUri();
}
$data[] = array(
'rocnik' => $node->get('field_rok')->getValue(),
'miesto' => $node->get('field_miesto_konania')->getValue(),
'fotografie' => $node->get('field_zbornik')->getValue(),
'foto' => $photo,
);
}

$nids = \Drupal::entityQuery('node')->condition('type', 'zbornik_a_foto')->execute();
$nodes = Node::loadMultiple($nids);
$data = array();
foreach ($nodes as $node) {
$fotoValues = $node->get('field_fotografie')->getValue();
$myvalues = array();
foreach($fotoValues as $val){
$myvalues[] = $val["value"];
}
$data[] = array(
'rocnik' => $node->get('field_rok')->getValue(),
'miesto' => $node->get('field_miesto_konania')->getValue(),
'fotografie' => $node->get('field_zbornik')->getValue(),
'foto' => $myvalues,
);
}
return array(
'#theme' => 'riadky_zazili',
'#data' => $data,
'#title' => 'Zažili sme',
);
Hope this helps you
thanks
