Performance with row()

[eluser]jamie young[/eluser]
Opinions on performance of these two blocks of pseudoish code (assuming PHP5)

Code:

$query = $this->db->query('SELECT * FROM table LIMIT 1');
$row = $query->row();
echo $row->col1;
echo $row->col2;
echo $row->col3;

Code:

$query = $this->db->query('SELECT * FROM table LIMIT 1');
echo $query->row()->col1;
echo $query->row()->col2;
echo $query->row()->col3;

Is there any performance difference at all between the above two blocks of code? I know they both work, just not sure what the long term effects of using one method over the other will have on a large CI project.

I bet the first one is faster because you are calling $query->row(); only once.

I agree. In the first example, the result row is generated three times from the database result.
