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
?>
