FAQ
How do I know my code is not compliant to latest PHP version
If your site breaks, doesn't load correctly, shows errors or shows Error 500, after switching PHP version from your hosting server or if your hosting provider changed PHP versions and your site starts failing to work as expected; most likely culprit is the PHP version and you need the upgrade
What's the benefit of upgrading to latest PHP version?
Bugs fixed in PHP versions, some are from security concerns, and other for improved performance. Upgrading to latest PHP can increase your application's performance up to twice it's current performance while making the site safer, up-to-date and following modern standards and technology.
