Moving to Windows Server 2008 Breaks PHP Application

I have a PHP form to created tables in a database. There are about 30 fields that users have to enter to created a new 'accou开发者_JAVA技巧nt'.

I had the program functioning 100% perfectly on a Linux server and we recently switched to a Windows Server 2008 server.

Since the change we have had one issue with the application.

When users want to create new 'accounts' they get an error. This does not happen when we have to edit existing accounts.

The error tells me that there is an Incorrect integer value for fields that have a number value thought the fields are not required.

By default the script would fill these fields out with zero if they are left blank but that apparently is not happening on the new server
