Set Apache2 to process .html files as php 8.0

I have setup php/apache according to this linode guide: https://www.linode.com/docs/guides/install-php-8-for-apache-and-nginx-on-ubuntu/

This seems to have worked, and I have an apache server that can serve files, and process .php files.

However, I am having the darndest time figuring out how to tell apache to process .html files with .php. Any modification I make to .htaccess (a-la- https://manage.accuwebhosting.com/knowledgebase/2492/Parse-HTML-As-PHP-Using-HTACCESS-File.html and similar) produce no change. I have also set AllowOverride All to the /var/www/ directory in /etc/apache2/apache2.conf. Additionally, most online information on the subject points to earlier versions of .php, with no specific reference to 8.0.

What can get apache to process .html with php 8.0?

Solution

You need to have module for this, confirm you have this line in httpd.conf, or add it there:

LoadModule mime_module modules/mod_mime.so

Also check if you have the modules/mod_mime.so file present on your system.

Then find or add module section in httpd.conf:

<IfModule mime_module>
    # following line will change mime type of .html file to php
    # and they will be handled as such
    AddType application/x-httpd-php .html
</IfModule>

Directive AllowOverride All will enable .htaccess files but you need the mime_module enabled too.

And of course restart the apache server after making configuration changes.
