uhm...
maybe I'm wrong to use map() function...
return $results->map(function($row) {
foreach ($row['content']->toArray() as $key => $value) {
$row[$key] = $value;
}
unset($row['content']);
return $row;
});
In my db I have only one row.
When I find all results the callback inside map() is called one time.
If I add first() to chain then it's called two times and the second time
$row['content'] is undefined because I unset it before so thrown fatal
error. Why is it called two times?
Suggestions?
