How to change Config/app.php "timezone"( Application Timezone) according to the selected option.

推荐答案

您可以使用Laravel帮助器功能config设置时区.但是，这只会影响您将收到的请求.

You can use Laravel helper function config to set timezone. However, this will affects only the request you will receive.

config(['app.timezone' => $timezone]);

如果您的目标是更改时区一次并在每个请求上运行，那么如何将更改后的时区保存在数据库或文件中呢?然后，为数据库编写查询或在app/config.php中读取文件，并在文件中更改索引时区的值.

If your goal is to change once the timezone and run on every request then what about saving the changed timezone in DB or in a file. Then, write a query for DB or read a file in app/config.php and change the value of index timezone in a file.

例如(文件示例):

当您更改时区时，它会保存在文件中.

When you changed the timezone it saves in a file.

file_put_contents("path/to/file", $timezone);

而且，在app/config.php

$timezone= file_get_contents("path/to/file");
return [
 . . .   
    'timezone' => $timezone,
 . . .
]
