You should place all your application logic in your PHP script.
Here's an example that was posted to the old list.

::::::::::::::
conditionaltest1.tmpl
::::::::::::::
<HTML>
<BODY>
{IMG}
</BODY>
</HTML>

::::::::::::::
conditionaltest2.tmpl
::::::::::::::
<!-- BEGIN img_block -->
img src="images/{IMAGE}" {IMGSIZE}<br>
<!-- END img_block -->

<!-- BEGIN swf_block -->
swf src="images/{IMAGE}" {IMGSIZE}<br>
<!-- END swf_block -->

conditionaltest.php

<?php
  include("template.inc");

  $testdata = array("image1.gif", "movie2.swf", "movie3.swf", "image4.jpg");

  $t = new Template(".","comment");
  $t->debug=0;

  # load the page from conditionaltest1.tmpl into "page"
  # load image tag from conditionaltest2.tmpl into "img_tags"
  $t->set_file(array("page" => "conditionaltest1.tmpl",
                     "img_tags" => "conditionaltest2.tmpl"));

  # extract from "img_tags" the block named "img_block", leaving a
  # reference to {img_block_tag}
  $t->set_block("img_tags", "img_block", "img_block_tag");

  # extract from "img_tags" the block named "swf_block", leaving a
  # reference to {swf_block_tag}
  $t->set_block("img_tags", "swf_block", "swf_block_tag");

  # loop through our test data
  for ($cc = 0; $cc < count($testdata) ; $cc++) {
    # set variables with substitution data
    $t->set_var("IMAGE", $testdata[$cc]);
    $t->set_var("IMGSIZE", "size");
    if (ereg("\.swf$", $testdata[$cc])) {
      $t->set_var("img_block_tag", "");        # delete the image block
      $t->parse("swf_block_tag", "swf_block"); # fill in the swf block
    }
    else {
      $t->set_var("swf_block_tag", "");        # delete the swf block
      $t->parse("img_block_tag", "img_block"); # fill in the img block
