.htaccess regex help needed

[adamou]

DirectoryIndex redir.php

Order deny,allow

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ([^_]+)[^\.html] Index.php?id=$1&id2=$2&id3=$3 [L]

Hey all so this is my .htaccess, I want the ability for it to split up the URL multiple times.

for example my url is

hello_there_how_are_you.html

and if I do print($_GET) in the php code, all that comes up with is array(id => hello, id2 =>,id3 =>)

I want to be able to continiously split the string, any advice here?

I wuold of thought I had to add a /g param to the regex but I have no idea how this is done through .htaccess
