Oracle PHP unixODBC RedHat Enterprise4

[twocyl]

We are trying to use PHP 4.3.9, PHP-ODBC 4.3.9 and unixODBC 2.2.11 with Oracles 10.2 odbc driver for Linux on Redhat Enterprise 4.  I can make the connection and SQL runs in ISQL, but when we try to run SQL in PHP code, we get the following in the ODBC trace file:

[ODBC][17431][SQLError.c][379]
                Exit:[SQL_SUCCESS]
                        SQLState = IM001
                        Native = 0xbff06338 -> 0
                        Message Text = [[unixODBC][Driver Manager]Driver does not support this function]

I can see that the connection gets established in the Oracle listener log.  I can't seem to get any select statement past this problem.  Does anyone have any good ideas for how to get this to work?
Thanks.
