How To Change Your PHP Version - PHP Config Guide

Overview

Please note: We will be updating to PHP version 8.0 in batches beginning in 2022. Keep an eye out for communications on when your account will be updated and what changes, if any, you will need to make. For more information on updating content for PHP compatibility, read our guide on What to do if your Site Does not Work with Newer Versions of PHP. To learn more about what is changing with PHP 8.0, please see PHP.net's release notes.

Our servers support PHP 7.3 and higher. PHP versions 7.3 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.

The process for updating your PHP version will depend on what type of account you have set up. Older accounts use the Legacy interface, while updated accounts will use the Rock interface.

Most customers should use Rock instructions.

How to Change Versions Using PHP Config (Legacy)

You can change your PHP version in Legacy accounts by following these steps:

  1. Log in to your justhost control panel.
  2. Under the Hosting tab, click cPanel in the submenu.
  3. Scroll down and look for the programming section, then click the PHP Config. 
  4. Select the version of PHP you're interested in using.
  5. Click Save Change.

Note: This option only works with Legacy Account. Please see below for Rock Instructions.

How to Change Versions Using MultiPHP Manager (Rock)

You can change your PHP version in Rock accounts by following these steps.

  1. Log in to your justhost control panel.
  2. Click on the Advanced tab from the side navigation menu to the left.
  3. In the SOFTWARE section, click MultiPHP Manager.
  4. Check the box next to the website(s) this PHP version will apply to.
  5. Choose the PHP Version, then click Apply.

Please note: If a domain is set to Inherit, it will automatically take on whatever PHP setting is assigned to the main domain.

Generate php.ini

To generate a new php.ini file:

  1. Log in to your justhost control panel.
  2. Click on the Advanced tab from the side navigation menu to the left.
  3. Under the Software section, select the MultiPHP INI Editor.
  4. Select the path by clicking on the drop-down menu under Basic Mode Selecting a location.
  5. Choose the domain name.
  6. Once you're done, scroll down and click Apply.

Note: If you have any further questions about configuring the php.ini file, there are extensive descriptions within the file itself. You may also check this article MultiPHP INI Editor and find more help at http://www.php.net/docs.php.

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.
