$query = $connect->prepare("SELECT firstname, lastname FROM users WHERE id = '$id'");

$query->execute();

$row = $query->fetch();

// $full_name = $row["firstname"] . " ".$row["lastname"];

$full_name = $row["firstname"] . " ".substr($row["lastname"], 0, 1).".";

return $full_name;

If i remove the line that is a comment ( // ), it will return $full_name, if its there then it wont work. I also tried commenting with #, but it still wont work(wont return anything) as soon as there is a codecomment

weird issue
