RC with PHP5

I'm having lot's of problems witha server migration I just did which has PHP5 (the new server, the old one used PHP4) and Horde+IMP (which as I read, will not support PHP5 in older versions).

The question is, is RC capable of working with PHP5 (I guess I will already be trying it when I get a responce, but wanted some opinions about the configuration).
