Question

I want to separate iteration results by comma, but it’s not an array. I want to do it in views, so code shouldn’t be long.

<?php foreach ($roles as $role): ?>
    <?php echo $role->title; ?>
<?php endforeach; ?>

Result object implements Countable, Iterator, SeekableIterator, ArrayAccess.

Not certain I understand what your asking (your code basically seems to do what you say?) the only thing i see missing is separate by comma.

<?php
$first=true;
foreach ($roles as $role) {
  if (!$first) echo ",";
  $first=false;
  echo $role->title;
}
?>

Or if caching is ok (string length isn’t too long):

<?php
$output="";
foreach ($roles as $role) {
  $output.=$role->title.",";
}
echo substr($output,0,-1);//Trim last comma
?>
