How do you "activate" a PHP script from a HTML file?

[SokrMan]

When the user clicks a link I need the PHP script to run.

Just make the link go to the php file.
<a href="myphpsrc.php">Click this link</a>

For PHP code to work you need to have the webpage renamed with a .php extension or else the code will not execute.
