Good day all, I have a bunch of files that are .html and I want to add some .php to them. It seems my 2 options are Convert .html to .php and 301 redirect or add this line of code to my .htaccess file and keep all files that are .html as .html AddType application/x-httpd-php .html My gut is that the 2nd way is better so as  not alter any SEO rankings, but wanted to see if anybody had any experience with this line of code in their .htaccess file as definitely don't wan to mess up my entire site 🙂 Thanks for any help!
