[Zope] PHP3 from external methods ?

Anyone have experience with accessing php3-scripts through external methods ? The nicest way would of course be to have the script act as external methods themselves ,just passing parameters in , and getting return values , but i expect you would have to put some kind of python wrapper between zope and php.. any thoughts on the subject ? - one of our coders wrote a payment system in php3 and oracle, and we would really like to interface zope with it.. The cleanest way would of course be to rewrite the whole thing in python , but, as usual, we don't have the time... -- Geir Bækholt geirh@funcom.com
