title: How to include PHP file in SHTML pages?
body: <p>I have a shtml file index.shtml in which I want to include a PHP file which performs some programing and returns HTML data. I am trying to include my PHP file but I don't know how to do that, I tried following but nothing is working, </p>
  
  <p>Following line is just printing an error, "<strong>[an error occurred while processing this directive]</strong> ":</p>
  
  <pre><code>&lt;!--#include file="/SSI/test.php"--&gt; 
  </code></pre>
  
  <p>This line is displaying some junk characters: </p>
  
  <pre><code>&lt;!--#include virtual="/SSI/test.php"--&gt; 
  </code></pre>
  
  <p>This line is doing nothing and displaying the command as is in the .shtml page</p>
  
  <pre><code>&lt;?PHP 
      include("/SSI/test.php");
  ?&gt;
  </code></pre>
  
  <p>Thanks</p>
