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).

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
