How to find the first match?

Question

Regular Expressions

There are links like

../product/deny/?id=1
../product/?id=1

htaccess should only process the first match, i.e. in this example only "product" (and pass it as $1 to the p key). And if there are subsequent arguments in slashes, then pass them as $2, probably to another key.
This is how it works now

RewriteRule ^(?!.*mypanel|public)(.*?)/$ index.php?p=$1 [L,QSA]

Lord, how difficult these regular expressions are for me ...

Answer 1

I propose to write 2 instructions:
RewriteRule ^([^/]+)/?$ /index.php?p=$1 [L,QSA]
RewriteRule ^([^/]+)/(.+)/?$ /index. php?p=$1&p2=$2 [L,QSA]
