How do I add PHP code/file to HTML(.html) files?

I can't use PHP in my HTML pages. For example, index.html. I've tried using both:

<? contents ?> 

and

<?php contents ?> 

Neither of these work. My server offers PHP, and when I use a the .php extension, it works properly. Is this a problem or do I have to change the preferences in php.ini?

Solution 1:

You can't run PHP in .html files because the server does not recognize that as a valid PHP extension unless you tell it to. To do this you need to create a .htaccess file in your root web directory and add this line to it:

AddType application/x-httpd-php .htm .html

This will tell Apache to process files with a .htm or .html file extension as PHP files.

Solution 2:

I think writing PHP into an .html file is confusing and anti-natural. Why would you do that??

Anyway, if what you want is to execute PHP files and show them as .html in the address bar, an easiest solution would be using .php as normal, and write a rule in your .htaccess like this:

RewriteRule ^([^.]+)\.html$ $1.php [L]

Solution 3:

In order to use php in .html files, you must associate them with your PHP processor in your HTTP server's config file. In Apache, that looks like this:

AddHandler application/x-httpd-php .html

Solution 4:

You can modify .htaccess like others said, but the fastest solution is to rename the file extension to .php

Solution 5:

Add this line

AddHandler application/x-httpd-php .html

to httpd.conf file for what you want to do. But remember, if you do this then your web server will be very slow, because it will be parsing even static code which will not contain php code. So the better way will be to make the file extension .phtml instead of just .html.
