Personally I think you should use file_get_contents() instead.

Unless you're doing only very basic substitution, you may need to
consider regex, and preg_replace().

All I'd change here, is that instead of reading the file into an
array, I'd load it into a string.

Depends on how it's implemented. When you 'compile' the script into
native php, you are having a highly optimised parser do the variabe
insertion. Your main problem here would be register_globals, so you
need to ensure that you initialise any variables used.

You could use a full featured tokeniser/parser(and you'd probably IIRC
find one in Pear), but it may perhaps be simpler, to simply use preg
to replace something like {foreach:var:list}, or whatever your
perfered syntax.
