PHP 7 has taken the open source community by storm, breaking records for speed,
which is, metaphorically, causing heads to turn. In its most fundamental sense,
the core engineering team has effected a major rewrite of the language but has
still managed to maintain backward compatibility to a high degree. PHP is a great
language for developing web applications. It is essentially a server-side scripting
language that is also used for general-purpose programming. PHP 7 is the latest
version, providing major backward-compatibility breaks and focusing on improved
performance and speed. This means you can maintain high traffic on your websites
with low-cost hardware and servers through a multithreading web server.
