pdo按编号选择行

Question

Trying to change over to PDO, and I am missing something simple?

OLD WAY

$query="SELECT * FROM database"
$result=mysql_query($query);

$data=mysql_result($result, 2, "value");

This gets me a value from row 3, using PDO the only way I can figure is:

$result->setFetchMode(PDO::FETCH_ASSOC)
$row = $result->fetch();
$row = $result->fetch();
$row = $result->fetch();
$thisone = $row['value'];

This way seems silly and indirect, is there a better way to select a row by it's number? I need the whole database queried for other variables, so changing the database SELECT statement won't work.

You can use fetchAll to get an array containing all rows. Then it's just a matter of grabbing the row you're looking for:

$rows = $result->fetchAll();
$third = $rows[2];
$value = $third['value'];
