    Parameters

    Examples

    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
