如何在laravel中添加和更新配置变量

Question

I have a config variable file which I'm using it in my controllers instead of mysql for faster performance.

But my problem is that I can only read from this config file and I can not add or update any value from it.

any suggestion how to update or add new values to this variable file :

my variable file which is stored in /config/Banners_size.php:

return [
    "normal_x970h90" => [
        'status' => 'enable',
        'value' => '500'
    ],

    "normal_x234h60" => [
        'status' => 'enable',
        'value' => '500'
    ],
]

my php code to add new array to it which is not working :

    $banners = Config('Banners_size');
    $banner = array(
        $request->input('size') => [
            'status' => $request->input('status'),
             'value' => $request->input('cost')
        ]
    );

   $bannerinfo = array_merge($banners, $banner);

   Config('Banners_size' , $bannerinfo);

The configuration files are read only files, you cannot add parameters to it programmatically.

$banners = config('Banners_size');

config('Banners_size' , $bannerinfo);

The above two lines, will act the same, and will both return the value of Banner_size.
