The following example shows an controller with a method, in which we change some values from the .env. Make sure, the entries you want to change, really exist in your .env. https://github.com/Brotzka/laravel-dotenv-editor
namespace App\Http\Controllers;
use Brotzka\DotenvEditor\DotenvEditor;
class EnvController extends Controller
{
public function test(){
$env = new DotenvEditor();
$env->changeEnv([
'TEST_ENTRY1' => 'one_new_value',
'TEST_ENTRY2' => $anotherValue,
]);
}
}
