ODBC: WBEM driver

[Petr Toman]

Hello,
I would like to access W2K Eventlog from PHP via ODBC - access to the
system is enabled by "WBEM Driver" (supplied on the W2K CD). My code
looks like this:

$connection = odbc_connect("W BEM Source", "", "")
or die(odbc_errorm sg());

$select = "SELECT * FROM Win32_NTLogEven t WHERE Logfile =
'Application'";

$query_result = odbc_do($connec tion, $select)
or die(odbc_errorm sg());

odbc_fetch_row( $query_result);
echo odbc_result ($query_result, 1);
odbc_close($con nection);

Error produced: "Warning: odbc_do(): SQL error: [Microsoft][WBEM ODBC
Driver][ISAM]Failed to obtain provider interface, SQL state S0000 in
SQLExecDirect".

I suspect I need to pass WMI namespace 'root\cimv2' to the
odbc_connect() function (like with
C:\WINNT\system 32\wbem\wbemtes t.exe) - but HOW? I've found only
examples for ASP or VB on the Internet. Thanks in advance.
