Here's a class for you that I wrote for my own uses, it reads fast template style templates where you encapsulate your output items in curly braces such as : {var}
it also allows you to set variable into the global scope via a template by using the set command as follows: {SET:VARIABLE=VALUE}
You can then call that variable as $GLOBALS['VARIABLE']
NOTE: The class is intended for use with Constants and GLOBALS, though you can pass in arrays as well.
The order of priority is GLOBAL -> CONSTANT -> Array So be careful with your naming.
An additional nicety is you can have the C style comment / / and it will strip it out.
I could make that feature a bit more robust, but it was just an afterthought and haven't gotten around to the other style comment, but you can have as many astericks after the slash as you want and it should work, handy for adding comments that you want private amongst developers within a template.
Like I said, I made it for my own use and it's handy for me, maybe you'll find it to your liking as well.
If you're looking for something more standard, you might want to check out fastTemplates.
anyway... here it is.
