I have saw the group of array like this:

And the array like this:

```php
[1] => Array (
    [bid] => 2
    [board_name] => Test1
    [create_date] => 2019-04-25 12:28:14
    )
[2] => Array (
    [bid] => 3
    [board_name] => Test2
    [create_date] => 2019-04-25 12:28:14
    )
[3] => Array (
    [bid] => 4
    [board_name] => Test3
    [create_date] => 2019-04-25 12:28:14
    )

```

How can it build `<tr>` for every two arrays?  

Like this:

```html
<tr>
  <td>Test1</td>
  <td>Test2</td>
</tr>
<tr>
  <td>Test3</td>
</tr>

```

Is it count every two arrays and then group them into new array?? 

I'm still learning about php, maybe this question is hard to be understood what I means, sorry for my bad English..
