问题 I have a basic silex application, and I try to test it using HTTPie. Yet when posting using: http POST http://localhost:1337 data="hello world" The data , that I get from the Request object via: $data = $request->request->get('data'); will always be empty.

问题 In a Silex application running on HVVM I have setup a dummy event listener on Kernel TERMINATE : $app['dispatcher']->addListener( KernelEvents::TERMINATE, function () use ($app) { usleep(10000000); $app['logger']->alert("I AM REGISTERED!"); } ); I was expecting my application to render the response as fast as possible within a second and after 10s I expected the message "I AM REGISTERED" to appear in my log.

问题 Using Doctrine DBAL, I have some code that inserts a new row into the main database from a form values binded as $telephone_international and $surname . After that is done, it inserts a new record into a duplicate database. $app['dbs']['backup'] If that's successful, the entry inserted previously the main database gets its copied value updated.
