Upgrade PHP version in project from 5.6 to 8.1

I need to upgrade PHP version of my project. It is PHP5.6 and I want to upgrade it to PHP8.1. I tried to search for such information but couldn't find it, thus, I want to ask. Is it better to upgrade directly from PHP5.6 to PHP8.1, or step by step (PHP5.6 -> PHP7.0, PHP7.0 -> PHP7.1, PHP7.1->PHP7.2 and etc until I reach PHP8.1)?

Solution

  • Upgrading step by step can help you to see what is deprecated by following the logs files and then review the code.
