On the SitePoint PHP blog there's a new post interviewing the company behind Appserver.io, an application server written for PHP and in PHP.
What if you could reliably run PHP without Nginx or Apache, but also without relying on its internal server? What if you could do async operations in PHP with true multi threading, fully taking advantage of multi core processors without hacks or a jungle of callbacks? What if you had drag and drop installation support for your PHAR packaged web apps in an environment identical to its production counterpart? Enter Appserver (application server).
They talk with Tim Wagner, Johann "Hans" Zelger and Stefan Wilkommer about the tool and what kinds of features it has to offer PHP developers. There's mention of "servlets", configuration of the platform and the results of some of the benchmarks they've run comparing it to other web servers. There's lots more in the full interview so be sure to check into it if you're intrigued by this interesting addition to the PHP world.
