Example #1 Setting the fetch mode
The following example demonstrates how PDOStatement::setFetchMode() changes the default fetch mode for a PDOStatement object.
<?php$sql = 'SELECT name, colour, calories FROM fruit';try { $stmt = $dbh->query($sql); $result = $stmt->setFetchMode(PDO::FETCH_NUM); while ($row = $stmt->fetch()) { print $row[0] . "\t" . $row[1] . "\t" . $row[2] . "\n"; }}catch (PDOException $e) { print $e->getMessage();}?>
The above example will output:
apple red 150 banana yellow 250 orange orange 300 kiwi brown 75 lemon yellow 25 pear green 150 watermelon pink 90
