Let .htaccess RewriteRule redirect to a script “in current dir” (instead of an explicit path)

Question

I\'m using a RewriteRule in .htaccess to redirect anything that is not an existing file, to a \"cms.php\" file which dynamically handles any request (or outputs some er

Typically, you'd just set a RewriteBase to the dev directory and leave the leading slash off of your rule's target:

RewriteEngine On
RewriteBase /subdir/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ cms.php [L,QSA]

But if that's not good enough, and you want to be able to move the htaccess file around arbitrarily without having to alter the base all the time, ou can try to do something crazy by detecting an arbitrary base:

RewriteCond %{ENV:URI} ^$
RewriteRule ^(.*)$ - [ENV=URI:$1]

RewriteCond %{ENV:BASE} ^$
RewriteCond %{ENV:URI}::%{REQUEST_URI} ^(.*)::(.*?)\1$
RewriteRule ^ - [ENV=BASE:%2]

at the very top of your htaccess file, then using the BASE environtment variable:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ %{ENV:BASE}cms.php [L,QSA]
