Running PHP on 64 bit Windows platform - issues?

Question

Hi,

We need to have our PHP application hosted on a 64 bit Windows OS due to another application's requirement. However, reading a bit more on the topic revealed that the PHP implementation is only for a 32 bit environment on Windows.

From: http://en.wikipedia.org/wiki/PHP

PHP interpreters are available on both 32-bit and 64-bit operating systems, but on Microsoft Windows the only official distribution is a 32-bit implementation, requiring Windows 32-bit compatibility mode while using Internet Information Services (IIS) on a 64-bit Windows platform. As of PHP 5.3.0, experimental 64-bit versions are available for MS Windows.[22]

Would running IIS on 32 bit mode cause potential problems with PHP?

What are the experiences people have had with such a setup?
