ASP.NET migrate to PHP

[IxiRancid]

I have a WebApplication written in vb.net. This application uses mostly complicated math equations and just a few textboxes to enter parameters.
Some of the functions (besides math) use date and time conversions in AddDate and DateDiff functions...

How could this be migrated to PHP, with what troubles etc.?

well mister
My app is to be sold, and I HOPE that they won't make me migrate to PHP.

well, php can invoke com objects. There's nothing stopping you from creating a ccw for your .net code. =D
