Before changing the PHP version
We recommend choosing the newest PHP version compatible with your Moodle installation and its plugins, and using the latest maintenance update in that branch. Prepare a backup and test the change before applying it to the live site.
Moodle 4.5, 5.0, 5.1, and 5.2 require 64-bit PHP. In addition to the PHP version, review the extensions and database requirements in your version's notes.
You can consult the official PHP compatibility documentation.
For an installation or upgrade to Moodle 5.2, review its official requirements.
