問題描述

我在我的項目中使用了一個包，它在 config/packagename

我想在配置文件中動態更改這個值，這是當前文件結構的樣子；

'118754561','cache_lifetime_in_minutes' =>60*24,];

我想把它改成這樣 -

'view_id' =>身份驗證::用戶()-> id，

您可以在配置文件中執行此操作，還是必須存儲某種變量以便稍后在控制器中更新.有沒有辦法將這些變量放在 env 文件中并從控制器訪問這些新變量?

這也是一個動態更新 .env 文件的通用解決方案(分別是單獨的鍵/值對)

1. 像這樣更改 config/packagename 中的設置:

<塊引用>

返回 ['view_id' =>環境('VIEW_ID'，'118754561')，等等...]

2. 在 .env 中添加一個初始值:

   VIEW_ID=118754561

3. 在適當的控制器(例如 AuthController)中，使用下面的代碼并像這樣調用函數:updateDotEnv('VIEW_ID', Auth::User()->id)

   受保護的函數 updateDotEnv($key, $newValue, $delim=''){$path = base_path('.env');//從當前環境中獲取舊值$oldValue = env($key);//有什么變化嗎?如果($oldValue === $newValue){返回;}//用改變的數據重寫文件內容如果(文件存在($路徑)){//用新值替換當前值file_put_contents($path, str_replace($key.'='.$delim.$oldValue.$delim,$key.'='.$delim.$newValue.$delim,file_get_contents($path)));}}

(如果您想讓此函數更通用，以便使用 .env 中的 key=value 對，其中值必須用雙引號括起來，因為它們包含空格，則需要 $delim 參數).

誠然，如果您有多個用戶同時在您的項目中使用這個包，這可能不是一個好的解決方案.所以這取決于你使用這個包的目的.

注意:如果您打算從其他類中使用它，當然需要將該函數公開.

I'm using a package within my project and it stores a setting inside config/packagename

I would like to dynamically change this value inside the config file, this is how the file structure looks currently;

<?php

return [
    'view_id' => '118754561',

    'cache_lifetime_in_minutes' => 60 * 24,
];

I would like to change it to something like this -

'view_id' => Auth::user()->id,

Can you do this within the config file, or do you have to store some sort of variable to be updated later within a controller. Is there a way to place these variables in an env file and access these new variables from a controller?

This also is a generic solution to dynamically update your .env file (respective the individual key/value pairs)

1. Change the setting in your config/packagename like so:

return [
    'view_id' => env('VIEW_ID', '118754561'),
    etc...
]

2. Add an initial value into .env:

   VIEW_ID=118754561

3. In an appropriate controller (e.g. AuthController), use the code below and call the function like this: updateDotEnv('VIEW_ID', Auth::User()->id)

   protected function updateDotEnv($key, $newValue, $delim='')
   {
   
       $path = base_path('.env');
       // get old value from current env
       $oldValue = env($key);
   
       // was there any change?
       if ($oldValue === $newValue) {
           return;
       }
   
       // rewrite file content with changed data
       if (file_exists($path)) {
           // replace current value with new value 
           file_put_contents(
               $path, str_replace(
                   $key.'='.$delim.$oldValue.$delim, 
                   $key.'='.$delim.$newValue.$delim, 
                   file_get_contents($path)
               )
           );
       }
   }
   

(The $delim parameter is needed if you want to make this function more generic in order to work with key=value pairs in .env where the value has to be enclosed in double quotes because they contain spaces).

Admittedly, this might not be a good solution if you have multiple users at the same time using this package in your project. So it depends on what you are using this package for.

NB: You need to make the function public of course if you plan to use it from other classes.
