PHP ODBC_connect与现有的ODBC驱动程序

Question

I have an ODBC Connection that works:

$cqmconn = odbc_connect("Driver={SQL Server Native Client 10.0};
Server=JOHN-HP;
Database=cqmla;", "sa", "sa") or die ("Unable to connect to CQM site.");

However, I have an existing ODBC Driver called "cqm2" that connects to cqmla, but the line beow does NOT make a connection:

$cqmconn = odbc_connect("cqm2","sa","sa") or die ("Unable to connect to CQM site.");

I can, however, use that ODBC connection (and credentials) with other software and it works fine. What am I missing?

I ask this because while I certainly can use the first method here, I have ANOTHER proprietary system that I cannot get to work, although it does have an ODBC connection I can access via other software using the: $cqmconn = odbc_connect("cqm2","sa","sa") format. If I can get my existing connection to work here, I figure I should then be able to call the other one.

What am I missing?

PS: I've tried adding SQL_CUR_USE_ODBC to the end of the call, but it changed nothing.

Answering my own question: It seems that odbc_connect() for PHP does NOT recognize User DSNs, only System DSNs. As a result, when I changed the DSN I was trying to use for a connection to a System DSN, I was able to use the: $cqmconn = odbc_connect("cqm2","sa","sa") paradigm.
