OK, now i know i will receive some scrutiny from some people here for "re-inventing the wheel", and they will tell me to just use Smarty, but, I have developed this simple template engine for my own purposes and i would like to share it with others here. Smart is very nice, and i would recommend it to anyone, but, this is a lot more simple, and a lot less bulky than Smarty, and is all i need. Plus, it was a great learning experience for me, so, below you can see how i built this template engine, and see a working demo here...
http://www.mct-hosting.com/template/mct/
go ahead and switch the template from default to mctStyle, and vise versa. i will post the code for both.
index.php
PHP Code:
<?php #index.php

// This will live in the admin panel once complete
if (isset($_POST['submitted'])) {
// Find the name of the theme that you want to change to
$getTheme = mysql_fetch_array(mysql_query("SELECT * FROM theme WHERE id=$_POST[newTheme] LIMIT 1"));
// Change the old theme to not active
$query = mysql_real_escape_string("UPDATE theme SET active=0 WHERE active=1 LIMIT 1");
// Make the selected theme active
$query2 = mysql_real_escape_string("UPDATE theme SET active=1 WHERE id=$_POST[newTheme] LIMIT 1");
// If both themes have been switched, show successful message
if(mysql_query($query) && mysql_query($query2)) {
echo "Successfully changed layout to $getTheme[themeName]!";
echo '<meta http-equiv="refresh" content="1;url='.$_SERVER['PHP_SELF'].'">';
// If there was an error changing status for the themes, show an error
} else {
echo "<strong>Error!</strong> There was a problem changing the layout.";

to make this all work, you will need a mysql database. here is mine.
