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