How to make a complex regular expression with logic?

Question

Regular Expressions

Help me compose a regular expression for the script https://jsfiddle.net/mavj2kdr/
it is necessary to replace it differently if the character is present

Answer 1

will it go through .htaccess?
there will be 3 lines

RewriteCond %{HTTP_HOST} ^www\.www\.ru [NC]
RewriteCond %{REQUEST_URI} /users\.php$ [NC]
RewriteCond %{QUERY_STRING} !role=shop_manager [NC]
RewriteRule ^(.*)$ Куда_нужно_но_тут_с_гет_запросом [R=301,L]

RewriteCond %{HTTP_HOST} ^www\.users\.php [NC]
RewriteCond %{QUERY_STRING} role=shop_manager [NC]
RewriteRule ^(.*)$ http://www.www.ru/users.php [R=301,L]

Accordingly, all these variables and the regular expressions themselves will be the same in php, but I’m not strong in pregmatch, so you are already getting more expensive, in principle, it will work even through .htaccess, but the redirect to GET does not work well in it
