Create an .htaccess file and upload it to the root of your public_html directory. Include the following lines...
RemoveHandler .html .htm
AddType application/x-httpd-php .php .htm .html
This code will tell Apache to treat all .html and .htm files as PHP files. This means that any time a user requests a .html or .htm file, Apache will first parse the file as PHP and then execute it.
Because these extensions will be processed as PHP with the above command, changing the permission on those file types to 755 may be necessary.
If the above line does not work use the following:
AddType application/x-httpd-php5 .php5 .php4 .php .php3 .php2 .phtml .html .htm
AddType application/x-httpd-php .php5 .php4 .php .php3 .php2 .phtml .html .htm
If using CloudLinux lsapi /LiteSpeed API, use the following:
AddType application/x-httpd-lsphp .php5 .php4 .php .php3 .php2 .phtml .html .htm
AddHandler application/x-httpd-lsphp .php5 .php4 .php .php3 .php2 .phtml .html .htm
You should only parse HTML files that you trust. If you parse an HTML file that contains malicious code, it could be executed on your server.
You should make sure that the PHP code in your HTML files is well-written and secure. If the code is not well-written, it could be vulnerable to security attacks.
