Have a look at some of the existing examples, such as in https://github.com/WordPress/WordPress-Coding-Standards/tree/develop/WordPress/Docs/Arrays to see how the <em> </em> tags are used to emphasise the key bit of the code examples.

Thanks @GaryJones, I've addressed the missing emphasis in fdd28c7.

@jaymcp Hi Jay,

Thanks for working on this! Looking good!

I've gone through it with a critical eye and while the code samples were correct as they were, I have a feeling changing them a little would make the problem the sniff flags more obvious for people to grasp.

As, with the changes I made, some lines would become too long for code samples in docs, I've also broken up the SQL queries over multiple lines.

Let me know what you think about these suggestions.

Thanks @jrfnl, I appreciate the thorough feedback. I have committed all of your suggestions 🙂

Thanks for the update @jaymcp and sorry for my slow response.

All good now. As far as I'm concerned, this is ready for merge.

For whomever merges this: please squash-merge.
