PDO 准备语句上的参数编号无效

我正在处理使用 PDO 类创建的一系列查询，在某些情况下，我的查询需要相同的参数。 我创建了一个在 foreach 语句中使用的数组，该数组保存数据，但有些变量来自外部，我可以在一个查询中使用这两个数据吗？

这个例子：

// $connection is the PDO object;
// $full_data contains:
// $full_data[$i]["address"]
// $full_data[$i]["phone"]
// $full_data[$i]["email"]
// $full_data[$i]["user_id"]
// $full_data[$i]["surname"] // not used but present
// $full_data[$i]["name"] // not used but present

$sql = "UPDATE users_table SET city = :address, phone = :phone, email = :email, admin_id = :admin_id, admin_name = :admin_name WHERE user_id = :user_id";
$statement = $connection->prepare ($sql);


$statement->bindParam (':admin_id', trim($admin_id), PDO::PARAM_INT);
$statement->bindParam (':admin_name', trim($admin_name), PDO::PARAM_STR);


foreach ($full_data as $value) {
    $ok = $statement->execute ($value);
    $num = $statement->rowCount ();
}

} catch (PDOException $e) {
    return $e->getMessage ();
}

该页面返回错误： SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens

到底是什么问题，在 UPDATE 语句上该技术有效

该死，几个小时后我发现了问题......

// $connection is the PDO object;
// $full_data contains:
// $full_data[$i]["address"]
// $full_data[$i]["phone"]
// $full_data[$i]["email"]
// $full_data[$i]["user_id"]
// ==> $full_data[$i]["surname"] // not used but present
// ==> $full_data[$i]["name"] // not used but present

查询中未保存数组数据["surname"] and ["name"]生成错误。 这好像是execute ();需要精确的数组数据结构。 我已经用这个解决了这个问题：

$sql = "UPDATE users_table SET city = :address, phone = :phone, email = :email, admin_id = :admin_id, admin_name = :admin_name WHERE user_id = :user_id";
$statement = $connection->prepare ($sql);

// must be removed ==> $statement->bindParam (':admin_id', trim($admin_id), PDO::PARAM_INT);
// must be removed ==> $statement->bindParam (':admin_name', trim($admin_name), PDO::PARAM_STR);

for ($i = 0; $i < count($full_data); $i++) {
    $full_data[$i]["admin_name"] = "the admin name";
    $full_data[$i]["admin_id"] = "100";
    unset ($full_data[$i]["surname"]); // IMPORTANT: must remove the unused vars
    unset ($full_data[$i]["name"]); // IMPORTANT: must remove the unused vars
}



foreach ($full_data as $value) {
    // bindParam can be avoided, but it's recommended for data type security
    $statement->bindParam(':address', trim($value['address']), PDO::PARAM_STR);
    $statement->bindParam(':phone', trim($value['phone']), PDO::PARAM_STR);
    $statement->bindParam(':email', trim($value['email']), PDO::PARAM_STR);
    $statement->bindParam(':admin_id', trim($value['admin_id']), PDO::PARAM_INT);
    $statement->bindParam(':admin_name', trim($value['admin_name']), PDO::PARAM_STR);

    $ok = $statement->execute ($value);
    $num = $statement->rowCount ();
}

} catch (PDOException $e) {
    return $e->getMessage ();
}
