Question

$sql='SELECT sender 
      FROM messages 
      WHERE message_id = :message_id';
$sender_result = $db->query($sql, array(':message_id'=>$message_id));
$sender = $sender_result->fetch();

I use this to execute above sql. How can I use $sender in the If.

Answer 1

if(isset($sender[0]))){
            return TRUE;
        }
        else {
            return FALSE;
        }
