Ah. Why not use str_replace?
And when you are using classes, you could as easily define a Variable
class with a Name and a Value method, and even a ToTemplate method that
puts the two pairs of curly braces around them.
If this is for a template engine, you probably have the name/value pairs
in a "named" array. In that case, a str_replace in a foreach loop does
the job just fine.
