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();
}
?>`

El resultado del ejemplo seria:

    apple   red     150
    banana  yellow  250
    orange  orange  300
    kiwi    brown   75
