How to include PHP file on SHTML pages?

Question

I have a shtml index.shtml file in which I want to include a PHP file that executes some program and returns HTML data. I am trying to include my PHP file, but I don’t know how to do it, I tried to follow, but nothing works,

The following line simply prints the error " [error processing this directive] ":

<!--#include file="/SSI/test.php"--> 

This line displays some unwanted characters:

<!--#include virtual="/SSI/test.php"--> 

This line does nothing and displays the command as is on the .shtml page

<?PHP 
    include("/SSI/test.php");
?>

thanks
