Multiple pages including one Class...

Hi Everyone, I am having a problem building a very complex site with many includes and classes... I am running into problems because Some pages try to include a file, and define a class which has already been defined... Is there a SURE way to make this type of error not happen? I have tried doing $incMyFile = 1 and then an IF when i go Include, but it is no use... One time or another, inside some function or another it ends up crashing... I also tried with DEFINE(), but sometime it ends up crashing... Would there be any use in making PHP more forgiving in this type of case (Like if you set something on the included file, then classes can be re-defined, and functions overried others?)
