[PHP-DB] How can I tell if Recordset is empty using MSSQL and ODBC?

[Karen Resplendo]

In VBscript an empty recordset returns the "End of File" marker:
 
If rs.EOF Then do nothing
 
How can I do this in PHP using MS SQL Server and ODBC drivers? Here is a peace of my 
code:

  $data= odbc_do($connectionSDWIS,"SELECT LabUserName, LabName, WhichProcess FROM 
LabLogin WHERE LabUserName='$loginUserName' AND LabPassword='$loginPassword'");
