Random things on PHP, Symfony and web development
The HTTP server H2O recently hit major milestone with version 2.0.0. The new release comes with new features and performance enhancements.
PHP 7 was made available on December 3rd 2015. It offers great improvements in performance and memory use, which are even more significant in resource limited environments like the Raspberry Pi. Together with MySQL 5.7 and the lightweight H2O web server it offers significant gains to performance in LAMP applications.
For people working with web sites and web applications, there is never a lack of new things to learn. HTTP/2 is one of these things. It will be in a very significant role in both the lives of developers and users of all web services. Somewhat contrarily it won't change anything to the users of these. Or even the developers.
Varnish is a popular reverse proxy which is used to accelerate page loading by caching copies as static HTML. Varnish does not support SSL/TLS, which is in practise required to take use of the new HTTP/2 protocol. This article describes one way of achieving high performance using Varnish and HTTP/2.
A week ago I setup this site on HTTP/2 and wrote a short article on running PHP with the H2O server. As a follow-up I decided to write a brief article on how many visitors actually used this new capability on the site.
