htaccess mod_rewrite多个查询字符串的路径

Question

I've been searching but I can't quite find what I'm after. I'm trying to find an elegant way to redirect my url path to the query string via htaccess and mod_rewrite.

The problem is that the path does not have a fixed amound of sub dirs and could be huge.

ie http://example.com/sub1/sub2/sub3/sub4/sub5/sub6/sub7 ...

Currently I just have a load of rules in my htaccess to capture these...

RewriteRule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/? /index.php?sub[]=$1&sub[]=$2&sub[]=$3&sub[]=$4&sub[]=$5 [QSA,L]
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/? /index.php?sub[]=$1&sub[]=$2&sub[]=$3&sub[]=$4 [QSA,L]
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/? /index.php?sub[]=$1&sub[]=$2&sub[]=$3 [QSA,L]
RewriteRule ^([^/]+)/([^/]+)/? /index.php?sub[]=$1&sub[]=$2 [QSA,L]
RewriteRule ^([^/]+)/? /index.php?sub[]=$1 [QSA,L]

... but there may be more, anyone know of a way to autoamtically parse these in to the query string?

If the paramater name is always the same, you could just rely on the rewrite engine to loop through them all:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)$ /index.php?sub[]=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(.+)$ /$2?sub[]=$1 [L,QSA]
