An example usage would be like so...



Test.html;

<?php
	$Name = "Hi";
	$Pass = "Google";
?>

</html>

Index.php;

 <?php
    include("Template.class.php");
    
    $Template = new Template('Test.php');
    
    $HTML = @file_get_contents('Test.html');
    
    $PHP = $Template->Create($HTML);
    
    $Template->Write($PHP);
    
    ob_start();
        include("Test.php");
        $Contents = ob_get_contents();
    ob_end_clean();
    
    echo str_replace(__FILE__, $Contents, __FILE__);
?>  

Output'd Test.php;

 <?php
    $Name = "Hi";
    $Pass = "Google";
?>
