VOOT (Vanilla Object Oriented Templates) is a
simple PHP class for creating Web pages with
templates. It supports user-defined HTTP headers,
and it is capable of processing PHP contained in
rendered templates. This class was written with
simplicity and flexibility in mind: templates can
take the form of any text-based file, and you can
define as many content placeholders as you like in
each template. To indicate a placeholder in a
template, you just surround a key word with
percentage signs.
