How to fix Optional parameter declared before required parameter?

Can someone help me fix these errors, please?

Code line:

function pagination($per_page = 5, $page = 1, $url = '', $total)

Code (markup):

I tried this, but it breaks my site layout:

function pagination($total, $per_page = 5, $page = 1, $url = '')

Code (markup):

I also found this code in my single.php:

echo pagination($limit,$page,$m_Cpageurl.'?mrpage=',$rows);

Code (markup):

Thank you in advance

 

hey, is this still relevant?

 

If you have PHP 8, you can call the function like this:
pagination(total: $kckhg)

 

I guess you'll want something like pagination(url: $u, total: $t);
