InterBase vs. (better say instead of) MySQL

Hi group, is it possible to develop a PHP Web site using NT 4 / InterBase and later run it on Red Hat 6.1 / MySQL. I mean, is the difference only changing the DB connect to mysql_pconnect and that's it (I don't mean unsopported PHP features or config differences ... ONLY the DB part of the scripts). Anyopne has experience with that ... Any help appreciated. Thanks to all of you! Marc P. S. ~ Greets go out to all people, who make the list what it is: the best PHP resouce! Fuck that "Trick or Treat! Bush or Gore!"- Crap!!! This is the wrong place to discuss such stuff ...
