Smarty template dilemma

I am trying to generate a page using Smarty templates. Everything works fine except that instead of parsing
{$Content} in content_table.html I get a raw PHP code from the source.php file. My question is how to make
Smarty parse PHP instead of displaying it? Many thanks.

template file: content_table.html
====================================
<table align="center" width="600">
<tr>
<td>{$Content}</td>
</tr>
</table>

template file: table.html
===================================
<table border="0" align="center">
  <tr>
    <td>{$ContentTable}</td>
  </tr>
</table>


file calling template:
====================================
<?php
include "../includes/class.smarty.phplevel2.php";
include "../includes/functions.php";

$pageTitle="Object-oriented";
$Table = ShowTable($pageTitle);
?>

<html>
<head>
      <title><?php print $pageTitle;?></title>
</head>

<body>
<?php print $Table;?>

</body>
</html>

source file: source.php
====================================
<?php

Some PHP code

?>


function file: functions.php
=================================
<?php
function GetContent($pageTitle){

      $arrFile=Array("Object-oriented"=>"source.php");
      //putting source.php code in a string                               
      $pageContent = file_get_contents(trim($arrFile[$pageTitle]));
            
return $pageContent;
}

function ShowTable($pageTitle){

$smarty = new SmartyPHP();

$pageContent = GetContent($pageTitle);

$smarty->assign(array("Content"=>$pageContent));
$ContentTable = $smarty->fetch("content_table.html");

$smarty->assign(array("ContentTable"=>$ContentTable))
                                
$Table = $smarty->fetch("table.html");

return $Table;

}
?>

you need to extract the variables from the html code first:

for only simple variables:
preg_match_all('/\\{\\$([a-zA-Z_][a-zA-Z0-9_]*)\\}/U', $HTMLCode, $matches);

for everything:
preg_match_all('/\\{\\$(.*)\\}/U', $HTMLCode, $matches);

now you'll have $matches[0] to have all the matched variables... and you replace them with the variable variables in $matches[1]

if (is_array($matches[0]) and count($matches[0])) {
      for ($i=0;$i<count($matches[0]);$i++) {
            $HTMLCode = str_replace($matches[0][$i], $$matches[1][$i], $HTMLCode);
      }
}

Side note.

Unless you are doing something I didn't grasp (like creating new Smarty plugin funcs), I would advise not mixing PHP and Smarty for output.
a PHP page would be better off leaving all the output for Smarty.

ie.
PHP:
----
...
$tpl = new SmartyPage;
... getting all the variables and doing calcs
$tpl->assign('Content', $mycontent);
$tpl->display('my_smarty_template.html');
// END OF PHP FILE
 ?>
---
and leave all the output from <html> to </html> to template(s).
