How does Laravel modify .env configuration through the background? When using the laravel framework to develop PHP programs, it is crucial to configure the .env file of the framework. This file needs to configure the database, database user, cache, etc. The following article mainly introduces you to the relevant information on how Laravel can modify the .env configuration file in a friendly way. Friends in need can refer to it. I hope to be helpful.

Preface

Do I have to modify the code every time I change .env? Can the .env file be configured in the background? In fact, it is very simple to implement. Add the following functions to your project

Sample code

function modifyEnv(array $data) 
{
 $envPath = base_path() . DIRECTORY_SEPARATOR . '.env';

 $contentArray = collect(file($envPath, FILE_IGNORE_NEW_LINES));

 $contentArray->transform(function ($item) use ($data){
   foreach ($data as $key => $value){
    if(str_contains($item, $key)){
     return $key . '=' . $value;
    }
   }

   return $item;
  });

 $content = implode($contentArray->toArray(), "\n");

 \File::put($envPath, $content);
}

Use

// 你可以更新你想要的任何值 key => value 
$data = [
 'APP_ENV' => 'your_environment',
 'APP_KEY' => 'your_key',
 'APP_DEBUG' => 'trueOrFalse',
 'DB_DATABASE' => 'test',
 'DB_USERNAME' => 'test',
 'DB_PASSWORD' => 'test',
 'DB_HOST' => 'localhost',
 'CACHE_DRIVER' => 'file',
 'SESSION_DRIVER' => 'file',
];

// 或者
$data = [
 'DB_HOST' => '127.0.0.1',
];

// 使用函数更新
modifyEnv($data);

How about it? Isn’t it very simple? Then you can configure Laravel’s .env file graphically through the background~
