I want a particular group of Web addresses to visit a Zend/MVC

/races/super-star
/races/race-57
/races/space-ace

and the other group of Web addresses to visit WordPress

/
/home.php
/staff/bios.php
/company/about.php

However , wordpress is within

/apps/wordpress

I can not learn how to do that with htaccess redirects

RewriteRule ^application/wordpress(/?)(.*)$ /$2 [NC,R=301,L]

do this:

RewriteRule ^/$ /applications/wordpress/?page=$1 [L]

RewriteRule ^([a-z0-9-]+).php$ /applications/wordpress/?page=$1 [L]

RewriteRule ^([a-z0-9-]+)/([a-z0-9-]+).php$ /applications/wordpress/?page=$1 [L]

the very first lines are for that / the 2nd lines are for /home.php the 3rd lines are for those web addresses within the form /staff/bios.php etc

and so far as your zend web addresses they do not need any rules.
