.htaccess - Redirecting all .HTML to .PHP pages but not from one directory? -

i converted .html pages on site .php. added following code .htaccess file:

redirectmatch permanent ^(.*)\.htm(l?)$ $1.php 

this works fine , .html pages re-direct .php pages.

my question is, there way limit files code affects?

more stop .html , .htm pages sub domain being redirected.

shop.domain.com 

i have other parts of website in sub-directory of root folder need end in .html , don't want .html extensions re-direct.

is there code or way this?

add .htaccess in web root / directory.

options +followsymlinks -multiviews rewriteengine on rewritebase /  rewritecond %{http_host} !^shop\.domain\.com$ [nc] rewritecond %{request_uri} !^/shop/? [nc] rewriterule ^([^/]+)\.html?$ $1.php [r=301,nc,l] 

this won't redirect sub-directory including shop. in case want allow (except shop) use

rewriterule ^(.+)\.html?$ $1.php [r=301,nc,l]
