Just as you upgrade WordPress itself to make sure you are protected against security vulnerabilities, you should do the same with PHP. In addition, upgrading PHP produces a significant speed increase. PHP 7.0 was a huge leap forward – more than doubling performance compared to 5.6. With version 7.3 we have seen another 20% – 25% increase compared to 7.0. 7.4 is also showing performance improvements over 7.3.
We highly recommend PHP 7.3, 7.4 or the latest version 8.0 as it’s much faster, resource-friendly, and more secure than its predecessors.
In this video I show you how to update your PHP version if your using Godaddy hosting, Cpanel.
