How can I pass the correct variables in a URL in PHP for my paging?

Answer 1

it's simple:

1. don't use $_SERVER['argv'][0], construct URL by yourself on every request.

2. use preg_replace to remove existing page variable from $_SERVER['argv'][0] then add new one:

   $url_without_page_var=preg_replace('/page=(\d+)/i','',$_SERVER['argv'][0]);
