htaccess url rewrite,remove querystring and file extension

问题

my current url is something like:

http://something.somedomain.com/about_us/profile.php?tab1=about_us

a more complicated on is: http://something.somedomain.com/exchange_hosting/feature/outlook_web_access.php?tab1=exchange_hosting&tab2=feature&tab3=outlook_web_access

i want to make them shorter:

http://something.somedomain.com/about_us/profile http://something.somedomain.com/exchange_hosting/feature/outlook_web_access

my .htaccess

#RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ /$1.php?tab1=$0&tab2=$1

Try following for two sizes. For more lengthier url you have to write more such rules.

RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/?$ $1/$2.php?tab1=$1&tab2=$2 [L]
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/?$ $1/$2/$3.php?tab1=$1&tab2=$2&tab3=$3 [L]
