In CIhtaccess, how do I write this rewrite rule?

I am currently using CodeIgniter. What is the effect I want on the apache server? p.com? P1545 can be parsed to p. commainindex? P1545 has never been written successfully. Please advise me to write this: {code...} I am currently using CodeIgniter, apache server

What I want now is

Http://p.com /? P = 1545 can be parsed to http://p.com/main/index? P = 1545

I haven't written it successfully. Please advise.

This is what I wrote:

  
       RewriteEngine On    RewriteRule ^\?p=(\w+)$ /main/index?p=$1 [QSA,PT,L]    RewriteCond %{REQUEST_FILENAME} !-f    RewriteCond %{REQUEST_FILENAME} !-d    RewriteRule ^(.*)$ index.php/$1 [L]

In Rewrite, the default rule collection does not contain parameters, that is, the following part of "hello", so your requirements can be converted to the following:

/->/Main/index

The corresponding Rewrite rules are:

  
       RewriteEngine On    RewriteRule ^/$ /main/index [QSA,PT,L]    RewriteCond %{REQUEST_FILENAME} !-f    RewriteCond %{REQUEST_FILENAME} !-d    RewriteRule ^(.*)$ index.php/$1 [L]
  

Please test

  
       RewriteEngine On    RewriteCond %{REQUEST_FILENAME} !-f    RewriteCond %{REQUEST_FILENAME} !-d    RewriteRule ^(.*)$ /main/index/$1 [L]
