Question

I want use mysql_data_seek with PDO from google search I found that it should looks like this:

$row0 = $result->fetch(PDO::FETCH_ASSOC, PDO::FETCH_ORI_ABS         


        

Answer 1

You could do it like this:

$c = 1;
$saved=null; 
while($row = $q->fetch()){
    if($c==4){
        $saved = clone $row;
    };
    $c++;
    somethingelse;
}

$saved will then contain the 4th element as an object with almost no extra overhead calculations.
