php - .htaccess remove trailing slash after file extension -

i have external links site referrer pages file extension , trailing slash after e.g.

http://example.com/folder/page.php/

i can not change these links, 301 redirect links format instead:

http://example.com/folder/page/

i've tried this, doesn't work:

rewriterule ^(.*)\.php\/$ /$1/ [r=301,l] 

any appreciated.

try in /.htaccess file

rewriteengine on rewritecond %{the_request} /([^.]+)\.php/? [nc]  rewriterule ^ /%1/ [nc,r,l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^([^/]+)/?$ /$1.php [l,nc]
