It is not possible for you to execute a PHP function from a file whose extension is .htm or .html.
If you want to perform something using PHP then the file extension must be .php. You can insert all the html tags in a PHP file.

1. You can't open a PHP page by double clicking on it like an HTML page
2. I would suggest to use XAMPP. Because the package has Apache webserver, MySQL Database Package, etc as a single installer.
3. You can install them by clicking some two three buttons which is definitely a lot simpler than invidual installation of web server, PHP, etc
4. After the installation of XAMPP (assuming that u r using Windows) you can save your php files inside C:\program files\xampp\htdocs folder which is the default web publishing directory.
5. To view your php file which is in the above mentioned folder open your browser and type http://localhost/thefilename.php
*thefilename.php can be anything you want
*the localhost can be replaced by your machine name
Hope this will help you to start the PHP script running
simple problem: setting up a php page
