How to radically change the design of one particular wiki page?

Question

PHP

Hello! The picture below clearly shows what I have at the moment and what I want to get.

I would like to create a page on the existing wiki site that will not contain anything extra, except for the necessary information. That is, it will essentially be a home page for the repair personnel of the plant. The main question is: is it possible to do this at all and in which direction to google?

Answer 2

$sum[0]["sum(yes)"]

Answer 3

There is a suspicion that the code with an error is written in [sum(yes)]
Try
$sum[0][0];
