If you have a URI that uses PATHINFO, here's how the redirection should work:
/topic/Office/Work ==> /topic.php/Office/Work
/update/Office/Work ==> /update.php/Office/Work/topic-> /topic.php
Here's a code example to implement Multiviews that uses PATHINFO:
# Multiviews example code...use this in a .htaccess file
RewriteEngine On
RewriteCond %{REQUEST_URI} !.+php*
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f
RewriteRule ^([^/]+)/?(.*)$ $1.php/$2 [L]
RewriteEngine On
RewriteCond %{REQUEST_URI} !.+php*
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f
RewriteRule ^([^/]+)/?(.*)$ $1.php/$2 [L]
