如何在Codeigniter/PHP中合并两行并获得单个数组？

Question

我正在编写Codeigniter，用于为单个用户分配多个角色。为此，我创建了一个具有以下值的表。

    Array
(
    [Id] => 1
    [Store_address_id] => 
    [Customer_ref_id] => 193
    [Role_ref_id] => 1
    [Email_alert] => 0
    [Sms_alert] => 0
    [Admin_view] => 0
    [Admin_save] => 0
    [Admin_delete] => 0
    [Master_view] => 1
    [Master_save] => 1
    [Master_delete] => 1
    [Business_view] => 0
    [Business_save] => 0
    [Business_delete] => 0
    [Analytics_view] => 1
    [Analytics_delete] => 1
    [Analytics_save] => 1
    [Promotion_view] => 1
    [Promotion_save] => 1
    [Promotion_delete] => 1
)

但是，在数据库中，我有多个行，因此我需要像下面这样的验证来获得值

+----+----+----+
| i/p|i/p | o/p|
+----+----+----+
| 0  | 0  | 0  |
+----+----+----+
| 1  | 1  | 1  |
+----+----+----+
| 1  | 0  | 1  |
+----+----+----+
| 0  | 1  | 1  |
+----+----+----+

我的桌子是这样的

我需要验证并将其作为一个数组进行提取。

按照我的意见，我建议在您的控制器中这样做：

// set a permissions array and set to default values of 0
$permissions =  array(
    'Email_alert' => 0,
    'Sms_alert' => 0,
    'Admin_view' => 0,
    'Admin_save' => 0,
    'Admin_delete' => 0,
    'Master_view' => 0,
    'Master_save' => 0,
    'Master_delete' => 0,
    'Business_view' => 0,
    'Business_save' => 0,
    'Business_delete' => 0,
    'Analytics_view' => 0,
    'Analytics_delete' => 0,
    'Analytics_save' => 0,
    'Promotion_view' => 0,
    'Promotion_save' => 0,
    'Promotion_delete' => 0,
);

// get the rows
foreach ($results as $row) {
    // get each col name and value
    foreach ($row as $key => $value) {
        // make sure it is a value needed for the permissions array
        if(isset($permissions[$key])) {
            // this value is a permissions value, is it a 1
            if ($value == 1) {
                // set the permissions array to 1
                $permissions[$key] = 1;
            }
        }
    }
}

这只是我输入它，所以没有测试它，可能有一些错误的。希望它有帮助。可能有更有效的方法来做到这一点，但是如果您只处理几行，就可以了。
