odbc_connect -- Connect to a datasource
Description
resource 
odbc_connect ( string dsn, string user, string password [, int cursor_type] )
     Returns an ODBC connection id or 0 (FALSE) on
     error.
    
     The connection id returned by this functions is needed by other
     ODBC functions. You can have multiple connections open at once as long as
     they either use different db or different credentials.
     The optional fourth parameter sets the type of cursor to be used
     for this connection. This parameter is not normally needed, but
     can be useful for working around problems with some ODBC drivers.
    
     With some ODBC drivers, executing a complex stored procedure may
     fail with an error similar to: "Cannot open a cursor on a stored
     procedure that has anything other than a single select statement
     in it".  Using SQL_CUR_USE_ODBC may avoid that error. Also, some
     drivers don't support the optional row_number parameter in
     odbc_fetch_row(). SQL_CUR_USE_ODBC might help
     in that case, too.
    
     The following constants are defined for cursortype:
    
     
        SQL_CUR_USE_IF_NEEDED
       
        SQL_CUR_USE_ODBC
       
        SQL_CUR_USE_DRIVER
       
        SQL_CUR_DEFAULT

     odbc_pconnect().
