I am trying to update my PHP Version from 5.6 to 7.3 and i realized i will have to generate this code. Let me point out to few notices on this dashboard on the panel. See attached for more information. Please kindly assist. 

Thanks

Assist with what? It's just an information page about PHPs OPcache, to adjust configuration to your needs , please see https://www.php.net/manual/en/opcache.configuration.php

Thanks for your timely response. What i need is a process video or instruction to configure updates from PHP version 5.6 to PHP version 7.3. I will be happy to work with your advise.

Thank you

That has nothing to do with any upgrade. It's just a part of php you can configure according to your needs. If you still refer to opcache...

Please guide me on how to configure opcache php to php7.3. Thank you

I'd say if you are unsure, best is to stick to the default values. They are just fine for most users.

I'm unsure but my wordpress site needs this for new features and i'm stuck. Kindly provide assist. I will be so glad

Well what's the error-mesaage/requirement of wordpress regarding opcache?

Here is my error message

So this is generally about a php upgrade. There are many many guides on the Internet if you just search on google. There are many ways to update php, depending on your needs your system your need for maintainability, etc.
