I use the include("template") method for this alla time, it works
great. Most especially for HTML emails coming from a web site to a
group of users, just slick as anything. include does basically just
what your print_greeting function does less the actual printout, but
using php variables instead of a str_replace. Also, this way the
templates can be stored elsewhere, outside the actual code base if
need be.
