Laravel 5.0, env() returns null during concurrent

2019-06-26 17:09发布

The problem is that when I try to get a config variable using env('setting') or \Config::get('setting'), sometimes it returns null.

For the testing reason I created a simple route:

Route::get('/test', function () {
    $env = env('SETTING');
    if (!$env) {
        \Log::warning('test', [$env]);
    }
});

Then I used apache benchmark. And the results were like this:

  • Calling only one request at a time (ab -n 100 -c 1 http://localhost/test) there were no problem, no records in the log file
  • Calling with 10 concurrent requests (ab -n 100 -c 10 http://localhost/test) I got about 20 lines like this: [2015-06-22 14:19:48] local.WARNING: test [null]

Does anybody know, what can be the problem? Is there something missing in my configuration or in php settings?

This happen to me as well. My workaround is in your config/app.php you have to add this:

'setting' => env('SETTING'),

Then when you want to get the setting config you have to do this:

$env = config('app.setting');
