How to limit the number of pages shown in a pagination?

Question

With this question that already has solution, I got as a result a paginação com PDO but I have one more problem that will possibly be the subject of a reward next week.

As you can see in the image below, I have this pagination with +/- 1000 properties that divided by groups of 12 per page, will return me a total of +/- 90 pages that will be written in pagination form making me have 3 or 4 lines showing numbers that will lose meaning and will look monstrously horrible.

How can I limit the number of pages to be shown by repurposing the code shown within the answered question present in it? If you think it necessary, I will replicate the code inside it here.

Answer 1

It’s easy to do that.

First set a link limit to be displayed before and after:

$lim = 3;

Then set the beginning of the display according to the current page and the limit:

$inicio = ((($pg - $lim) > 1) ? $pg - $lim : 1);

_{If subtraction is greater than 1, start from it, but not more than 1.}

Then set the final limit:

$fim = ((($pg+$lim) < $qtdPag) ? $pg+$lim : $qtdPag);

_{If the sum is less than the final amount, then finish with it, if not with the final amount.}

And finally, define the loop starting and ending with these rules:

if($qtdPag > 1 && $pg <= $qtdPag){
   for($i = $inicio; $i <= $fim; $i++){

      if($i == $pg){
         echo "<li><a class='ativo'>".$i."</a></li>";
      } else {
        echo "<li><a href='busca?pg=$i'>".$i."</a></li>";
      }

   }
}

If the user is on page 5, the links that will be displayed are:

[2] [3] [4] 5 [6] [7] [8]
