下面的代码插入两次单个记录 .
注意：
除了下面的内容之外，脚本中没有其他代码（DB_HOST，DB_NAME等常量除外） .
码：
$dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''));
$array = array(
'2' => '13'
);
$sql = "INSERT INTO htdopen.oc_product_option (product_id, option_id, required)
VALUES (:product_id, :option_id, '1')";
$stm = $dbh->prepare($sql);
foreach ((array)$array as $key => $val)
{
$stm->bindParam(':product_id', $key, PDO::PARAM_INT);
$stm->bindParam(':option_id', $val, PDO::PARAM_INT);
$stm->execute();
}
输出:(记录输入两次，而不是一次）
+-------------------+------------+-----------+-------+----------+
| product_option_id | product_id | option_id | value | required |
+-------------------+------------+-----------+-------+----------+
| 1 | 2 | 13 | | 1 |
| 2 | 2 | 13 | | 1 |
+-------------------+------------+-----------+-------+----------+
编辑：
我更改了代码以在屏幕和计数器上输出内容 .
$dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''));
$array = array(
'2' => '13'
);
$sql = "INSERT INTO htdopen.oc_product_option (product_id, option_id, required)
VALUES (:product_id, :option_id, '1')";
$stm = $dbh->prepare($sql);
$c = 0;
foreach ((array)$array as $key => $val)
{
$c++;
echo $c . '. ' . $key .'=>'. $val . ' ';
$stm->bindParam(':product_id', $key, PDO::PARAM_INT);
$stm->bindParam(':option_id', $val, PDO::PARAM_INT);
$stm->execute();
}
....这是屏幕上的输出 - 单行 - 但又添加了2条记录......很奇怪：
