如何在PHP中为新创建的数组添加关联数组？

Question

我有一个名为$val的数组。这是一个空白数组。我希望以下面的方式，即在print_r($val);之后它应该按照以下方式打印数组$val：

我也关注变量：

$_POST['fileName'] = 'Sample_1.docx';
$_POST['fileLink'] = 'https://www.filepicker.io/api/file/HEYQ6lPNRg2lzjUNhUGX';

Array
(
    [status_info] => 
    [user_status] => Share what's going on...
    [group_id] => 
    [action] => upload_photo_via_share
    [is_activity_feed] => 1
    [vshare] => Array
        (
            [Sample_1.docx] => Array
                (
                    [0] => https://www.filepicker.io/api/file/HEYQ6lPNRg2lzjUNhUGX
                )

        )

    [link] => Array
        (
            [url] => http://
        )

    [poll_question] => 
    [answer] => Array
        (
            [0] => Array
                (
                    [answer] => 
                )

            [1] => Array
                (
                    [answer] => 
                )

        )

    [is_profile] => no
    [iframe] => 1
    [method] => simple
    [document_title] => document
    [category] => Array
        (
            [0] => 
        )

    [code_snippet] => 
)

我想在变量$val中添加以下结构。这件事应该只使用PHP代码完成。

如何在PHP中向数组$val添加以下键值结构？

提前致谢。

此数组的PHP源代码应如下所示：

$val = array(
    'status_info' => '',
    'user_status' => 'Share what's going on...',
    ...     
    'vshare' => array(
        'Sample_1.docx' => array (
            'https://www.filepicker.io/api/file/HEYQ6lPNRg2lzjUNhUGX'
        )
    ),

    'link' => array(
        'url' => 'http://'
    ), 

    ...
);
