Environment:
  Binary distro of PHP 4.0.2
  NT 4.0 (SP5)
  Apache 1.3.2
  Interbase ISQL Version: WI-V6.0.0.627
  InterBase/x86/Windows NT (access method), 
  version "WI-  V6.0.0.627" on disk structure version 10.0

When I try to fetch a record using ibase_query that is encapsulated into a class, it does not work and I receive:

"Warning: InterBase: invalid transaction handle (expecting explicit transaction start) in c:\program files\apache group\apache\htdocs\ibasetest.php on line 30"

Run the following script to duplicate.  Note that if you comment lines 2-19 and 38-48, you will run the fetch without creating the object.  In this case (non-object), the fetch works.

BTW - The uncommented (i.e., object version) works great on my Linux box (PHP 4.0.0 + Interbase 6.0).

Thanks.
P.S. If you need interbase testing or test scripts, I would be happy to help.  The interbase DLL is *really* shaky in NT for PHP 4.0.2.
