I am going to be upgrading from codeigniter 3.1 to codeigniter 4.0. I understand that I first need to upgrade php on my Ubuntu 18.03 to from v5.6.4 to version 7.4+. What are the steps I need to follow?

  • Please check your details; there was no Ubuntu release in 2018-March (18.03). – guiverc Mar 01 '23 at 23:06

    You are going to want to first test your PHP code on a system running PHP 7.4 (or newer) as a lot of the older syntax has been completely removed. Once you have confirmed that your PHP code works, then you can begin the process of upgrading PHP on the server. Otherwise you're going to have a much harder time of determining why something might be broken – matigo Mar 01 '23 at 23:55
