[php] How can I run a PHP script inside a HTML file?

thanks for the ideas but none works here. So i did that... I am using xampp last version on 2014. go to \xampp\apache\conf\extra\httpd-xampp.conf.

we will find this bit of code:

<IfModule php5_module>
    **<FilesMatch "\.php$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

Focus on second line, so we must to change to:

<IfModule php5_module>
    **<FilesMatch "\.(php|html)$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

And that is it. Works good!
