PHP
PHP – the server-side programming language powering over 80% of the web – is now at version 7.1.

If you’re just getting started with PHP, here are some introductory materials to get you up to speed.

Another of my widely used PHP snippets is this timing function, which can be used to time a whole script execution, or a single function. This is especially important for optimising script performance and reduction of page load times.
