It's stats o'clock! See 2014, 2015, 2016.1, 2016.2, 2017.2 for previous similar posts.
A quick note on methodology, because all these stats are imperfect as they just sample some subset of the PHP user base. I look in the <a href="https://packagist.org/>packagist.org logs of the last month for Composer installs done by someone. Composer sends the PHP version it is running with in its User-Agent header, so I can use that to see which PHP versions people are using Composer with.
The remainder of the post shares some of the results and differences since November 2017. Among the highlights are:
- The use of PHP 7.2 has increased by a large percent
- The use of all over versions (including PHP 7.1) is dropping
- There is still a large number of packages that only require a version in the PHP 5.x range to be installed
Check out the full post for the complete stats on versions in use and trends (along with some nice graphs of the results).
