The banner you are seeing actually contains an explanation. You even got a comment from one of the users involved in closing your question that explicitly asks you to "elaborate what the instructions are to accomplish".

To phrase that in a little less complicated english:

We can see that you have some code. It seems to be doing what you want it to do. It's really difficult to understand what exactly you want by reading the code.

So you've been asked to explain better what the code does. It would probably help if you visually separated the output you expect from how PHP would var_dump it. It would probably also help to put the output you expect into a "quote block" to make clear that it's not the code you want reviewed.

As it is, your question is really hard to grasp when "just reading through it".
