我在我的服务器上运行 PHP 5.4.4，用./configure. 我有带有 SQLite 3.7.7.1 驱动程序的 PDO。我创建了以下表格。

CREATE TABLE IF NOT EXISTS
login (
    id PRIMARY KEY ON CONFLICT REPLACE,
    given_name,
    family_name,
    gender
);
CREATE TABLE IF NOT EXISTS
address (
    id,
    street,
    city,
    state,
    zip,
    FOREIGN KEY(id) REFERENCES login(id) ON DELETE CASCADE
);
CREATE TABLE IF NOT EXISTS
certification (
    id,
    certification,
    certification_expiration,
    FOREIGN KEY(id) REFERENCES login(id) ON DELETE CASCADE
);

而这个观点。

CREATE VIEW "members" AS SELECT
    login.id, login.given_name, login.family_name, login.gender,
    address.street, address.city, address.state, address.zip,
    certification.certification, certification.certification_expiration
FROM
    login, address, certification
WHERE
    login.id = certification.id
    AND
    login.id = address.id

我正在查询这样的视图：

<?php   foreach ($sql->query('SELECT * FROM members;') as $row):    ?>
                    <tr>
<?php       foreach ($row as $index => $col): ?>
                        <td><?=$index;?>.<?=$col;?></td>
<?php       endforeach; ?>
                    </tr>
<?php   endforeach; ?>

它正在产生这样的输出。

            <tr>
                <td>id.123456789012345678901</td>
                <td>0.123456789012345678901</td>
                <td>given_name.Mark</td>
                <td>1.Mark</td>
                <td>family_name.Tomlin</td>
                <td>2.Tomlin</td>
                <td>gender.Male</td>
                <td>3.Male</td>
                <td>street.1 Some Lane</td>
                <td>4.1 Some Lane</td>
                <td>city.Anywhere</td>
                <td>5.Anywhere</td>
                <td>state.NY</td>
                <td>6.NY</td>
                <td>zip.12345</td>
                <td>7.12345</td>
                <td>certification.AEMT-P</td>
                <td>8.AEMT-P</td>
                <td>certification_expiration.2015-07-31</td>
                <td>9.2015-07-31</td>
            </tr>

我想知道，为什么它给我id.and 0.， and given_name.and 1.，还有什么我可以从查询中过滤掉这种行为吗？我想得到只是id.或只是0.但不是两种类型。

这修复了它

$sql->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);

帽子提示，biziclop为助攻。
