We are constantly dedicated to bringing you the latest stable versions of PHP as soon as we have thoroughly tested it throughout our environment.
PHP 7.4.0 was released for general availability (GA) on November 28th, 2019 and we are excited to let you know this is now available on MyKinsta. Previously we had the RC version available for testing, but you can now start thinking about updating your production sites.
We’ll be releasing our annual PHP benchmarks report within the next couple of weeks so you can see how much this new version will impact the performance of your sites. Spoiler alert: PHP 7.4 is faster than PHP 7.3. 🚀
Upgraded my @kinsta site to PHP 7.4 and it is like 10x faster. Woot!

Update to PHP 7.4
You can easily change PHP versions from within the MyKinsta dashboard, under Tools, with a single click.
In the MyKinsta dashboard, click into your site and change the environment over to the “Staging environment.”
You can then change the PHP Engine for the staging site under “Tools” and start testing to ensure the compatibility of your code, third-party plugins, and themes. Once you confirm everything works, you can either change your production site over to PHP 7.4 or if you’ve made any changes, also push your staging site to live.
Remember that you can switch PHP engines back and forth, so if you encounter compatibility issues with PHP 7.4, you can easily resort back to PHP 7.3. If you were already running an RC version of PHP 7.4, your sites have already been automatically updated to PHP 7.4.
