Hello Dev!

Today i'll show how to update laravel .env dynamicely from backend with database store.

First you have to create a customer helper function. If you don't know how to create Helper Function please Clicke here.

Step 1. Go to helper function.

public static 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)
            )
       );
   }
}

Step 2. without database store

//Here we update email configyration in .env

public function emailConfigUpdate(Request $request)
    {   

        Helper::updateDotEnv('MAIL_MAILER',$request->driver);
        Helper::updateDotEnv('MAIL_HOST',$request->host);
        Helper::updateDotEnv('MAIL_PORT',$request->port);
        Helper::updateDotEnv('MAIL_USERNAME',$request->user_name);
        Helper::updateDotEnv('MAIL_PASSWORD',$request->password);
        Helper::updateDotEnv('MAIL_ENCRYPTION',$request->encryption);
        Helper::updateDotEnv('MAIL_FROM_ADDRESS',$request->sender_email);
        Helper::updateDotEnv('MAIL_FROM_NAME',$request->sender_name);

        return redirect()->back()->with('success','Successfully Updated!');

    }

Step 3. with database store

//Here we update email configyration in .env and database

public function emailConfigUpdate(Request $request)
    {   
        $data = EmailConfig::first();
        $data->driver       = $request->driver;
        $data->host         = $request->host;
        $data->port         = $request->port;
        $data->encryption   = $request->encryption;
        $data->user_name    = $request->user_name;
        $data->password     = $request->password;
        $data->sender_name  = $request->sender_name;
        $data->sender_email = $request->sender_email;
        $data->save();

        Helper::updateDotEnv('MAIL_MAILER',$request->driver);
        Helper::updateDotEnv('MAIL_HOST',$request->host);
        Helper::updateDotEnv('MAIL_PORT',$request->port);
        Helper::updateDotEnv('MAIL_USERNAME',$request->user_name);
        Helper::updateDotEnv('MAIL_PASSWORD',$request->password);
        Helper::updateDotEnv('MAIL_ENCRYPTION',$request->encryption);
        Helper::updateDotEnv('MAIL_FROM_ADDRESS',$request->sender_email);
        Helper::updateDotEnv('MAIL_FROM_NAME',$request->sender_name);

        return redirect()->back()->with('success','Successfully Updated!');

    }
