How to reorganize posts before outputting

I have an article application. Normally I do not have any recommendation system other than getting latest 100 data from database and than recommending them depending on like count. I wonder how I can get the data into an array and than do some math before outputing. I have an idea but couldn't find anything useful about how to do it in the internet.

So lets say I have this query:

$articles = Article::orderBy('id', 'desc')->take(100)->get();

Now what I want to do is creat another array with size of 100 and place each article id one by one but depending on my algorithm.

before I start I want to give you everything that will be used:

$article->likecount 
$article->viewcount 
$article->user->reputation  
$article->category->interest  

I will use these values in orther to re-order last 100 articles and than paginate them.

Here is what I need:

• I need to get $article->likecount
• Add $user->reputation
• Add the $category->interest
• Result minus $article->viewcount

And than put this value inside the array. Array needs to be ordered smallest to the largest.

I can do something simular in C or C++ but I do not know enough syntax to accomplish this in raw PHP or Laravel
