Overview

Warning: PHP versions PHP 7.3, PHP 7.4, and PHP 8.0 are deprecated. We recommend that you update to a supported version of PHP. For more information, read cPanel's PHP documentation.

PHP versions 8.1 and higher offer a significant improvement to speed and memory usage over past PHP versions. It also comes with better error handling and many bug fixes.

Before making the switch, you need to be aware of backward compatibility issues with scripts: Older PHP coding may not be compatible with newer PHP versions. Therefore, ensure to "Avoid skipping versions," and instead, "make updates incrementally."

It is important to check first the "Compatibility" of your site against new versions of PHP before upgrading. Sites built with WordPress can use the PHP Compatibility Checker plugin. You can also check PHP Manual for reviewing the new and deprecated features of PHP.

Pro Tip: In addition to making sure you have the latest PHP, make sure your data and files are also protected in the event of accidents, data loss, or hackers with  CodeGuard. Ensure you have a daily backup of your site for easy restoration. To know more information about this process, please see: Getting CodeGuard Set Up for Backups or How To Backup & Restore WordPress Using WordPress Tools.

What is php.ini?

The php.ini file is the default configuration file for running applications that require PHP. It is used to declare settings and control variables such as upload sizes, file time-outs, resource limits, etc. 
Your server is already configured with standard settings for PHP, which your site will use by default. Unless you need to change one or more settings, there is no need to create or modify a php.ini file.

Note: If you would like to make any changes to these settings, please do so through the MultiPHP INI Editor. To know more about the process, please see: How To Configure The PHP Environment With PHP ini.

Things to Keep in Mind

If you are using a custom php.ini file that references PHP modules that are not available in your selected version, your site may not work. Either remove the custom php.ini file (which will cause the server to use the default php.ini file) or create a php.ini file compatible with your selected version.
