Redirect with htaccess using first letter of "folder name" to specify php file to use

Question

I have the following rule:

RewriteRule ^([a-z])([\w-]+)/?$ $1.php?var=$2 [L,QSA,NC]

This redirects /fH128 to f.php?var=H128. I would like to be able to have the first character, which identifies the file name, be uppercase, but then redirected to this filename in lowercase. Thus /FH128 would redirect to f.php?var=H128.

I tried the following, but neither work:

RewriteRule ^([a-z])([\w-]+)/?$ ${lowercase:$1}.php?var=$2 [L,QSA,NC]
RewriteRule ^([a-z])([\w-]+)/?$ {lowercase:$1}.php?var=$2 [L,QSA,NC]

Inside your Apache config files e.g. httpd.conf or virtual host config (but not .htaccess) define this RewriteMap:

RewriteMap lowercase int:tolower

Then inside .htaccess use your rule as:

RewriteRule ^([a-z])([\w-]+)/?$ ${lowercase:$1}.php?var=$2 [L,QSA,NC]
