I know that in PHP 4 there is such a function, but I do not know exactly
what it is. Also, because the template scheme that I am proposing is
object-oriented, it would not be very difficult to get a string instead of
printing. However, printing with include() is more efficient.

You could just load the data out of the file using PHP's file API, and then
eval() the whole thing at a later date. This would not be too difficult.

It is possible that the error you describe is a result of PHP4 - I have not
yet tested EnzymeTemplates with PHP4. If you could uncomment some of the
DEBUG lines in ET, and send me that output, I would greatly appreciate it.
