/**

 * certainly need a good ODBC reference to explain all the different
 * options and values that can be used.  Different driver versions

 * this function in scripts to be made publicly available is
 * strongly discouraged.  Also, some ODBC options are not available
 * to this function because they must be set before the connection
 * is established or the query is prepared.  However, if on a
 * particular job it can make PHP work so your boss doesn't tell you
 * to use a commercial product, that's all that really
 * matters.
