For anyone out there still having trouble,
try this (my hosting was from Godaddy and this is the only thing that worked for me among all the answers out there.
AddHandler x-httpd-php5-cgi .html
here put this in your .htaccess
AddType application/x-httpd-php .php .htm .html
more info on this page
Using @Marc-François approach Firefox prompted me to download the html file
Finally the following is working for me (using both):
AddType application/x-httpd-php .htm .html
AddHandler x-httpd-php .htm .html
I'm using PHP7.1 running in my Raspberry Pi 3.
In the file /etc/apache2/mods-enabled/php7.1.conf
I added at the end:
AddType application/x-httpd-php .html .htm .png .jpg .gif
First, read this: https://httpd.apache.org/docs/current/howto/htaccess.html#when
Then read my post here: https://stackoverflow.com/a/59868481/10664600
sudo vim /etc/httpd/conf/httpd.conf
I think this is the best way to run php script on html and htm pages:
AddType application/x-httpd-php5 .html .htm
Running .html files as php stopped working all of a sudden in my .htaccess file.
Godaddy support had me change it to:
AddHandler application/x-httpd-lsphp .html
You may also use the H or T flag of mod_rewrite to force all .html files to be parsed by php handler :
using H (Handler) flag:
RewriteEngine on
RewriteRule \.(html|htm)$ - [H=application/x-httpd-php5]
using T (Type) flag :
RewriteEngine on
RewriteRule \.(html|htm)$ - [T=application/x-httpd-php5]
Or you can add more extensions to the rule pattern seprated by a pipe | that you want to be parsed by php handler
ex :
RewriteRule \.(html|htm|txt|foo)$ - [T=application/x-httpd-php5]
the example above will change the mime type of files that end with .html , .htm , .txt , .foo to php.
Note : on some servers you will have to change php5 to php to get this example to work in handler string:
Change it
[T=application/x-httpd-php5]
to
[T=application/x-httpd-php]
This is in edition to all other right answers:
If you are not able to find the correct Handler, Simply create a .php file with the following contents:
<?php echo $_SERVER['REDIRECT_HANDLER']; ?>
and run/open this file in browser.
Use this output in .htaccess file
Create a .htaccess file at the root of your website(usually a folder named public_html or htdocs on linux servers) and add this line:
AddType [[THE OUTPUT FROM ABOVE FILE]] .html .htm
Example
AddType application/x-httpd-php70 .html .htm
If you see blank page or Notice: Undefined index: REDIRECT_HANDLER
Try default in .htaccess
AddHandler application/x-httpd-php .html
None of the answers posted here worked for me.
In my case the problem was, by the one hand, that the .conf file (/etc/apache2/sites-available/default-ssl.conf or /etc/apache2/sites-available/000-default.conf) did not contain the directive AllowOverride All
for the site directory, which caused the .htaccess to not been processed. To solve this, add:
<Directory /var/www/html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
On the other hand, the problem was that the .htaccess was created by the root user, and therefore the apache user could not read it. So, changing the file owner solved definitely the problem:
chown www-data:www-data .htaccess
AddHandler application/x-httpd-php .php .html .htm
// or
AddType application/x-httpd-php .php .htm .html
Normally you should add:
Options +ExecCGI
AddType application/x-httpd-php .php .html
AddHandler x-httpd-php5 .php .html
However for GoDaddy shared hosting (php-cgi), you need to add also these lines:
AddHandler fcgid-script .html
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .html
On Dreamhost Servers you can refer to this page that at time of writing indicates you may use the following for php 7.2 with FastCGI:
AddHandler fcgid-script .html
FcgidWrapper "/dh/cgi-system/php72.cgi" .html
Or if you are using php5 cgi (not FastCGI):
AddHandler php5-cgi .html
You need to add the following line into your Apache config file:
AddType application/x-httpd-php .htm .html
You also need two other things:
Allow Overridding
In your_site.conf
file (e.g. under /etc/apache2/mods-available
in my case), add the following lines:
<Directory "<path_to_your_html_dir(in my case: /var/www/html)>">
AllowOverride All
</Directory>
Enable Rewrite Mod
Run this command on your machine:
sudo a2enmod rewrite
After any of those steps, you should restart apache:
sudo service apache2 restart
In My Godaddy Server the following code worked
Options +ExecCGI
AddType application/x-httpd-php .php .html
AddHandler x-httpd-php5 .php .html
