PHP returning empty datasets (Redhat -> Openlink ODBC -> MS Access)

Have anyone had anyone have problems with being able to connect to a Access DB fine, but not 'see' anything? I changed my setup (Win2000 to Linux) which WAS working fine, and now the whole thing doesn't seem to work. Setup: PHP 4.0.3sp1 (+Apache 1.3.12) -> Openlink (redhat) -> Openlink (win98) -> Access97 MDB No errors are in the logs; no warnings produced anywhere. openlink's odbctest program [on linux machine] can read data FINE ... SQL statements all seem to work perfecltly. PHP can odbc_connect() fine, but all other functions - table 'width' (number of columns etc), SELECT queries etc all are "successful" (ie, dont produce errors or warnings), but don't return anything - i have a 20,000 row table which strangely is completely empty to PHP :( Any ideas? Strangely, the code I use works fine on this previous setup: [Win2000 machine] PHP403sp1 (IIS 5.0)->Openlink DSN->Access DSN -> Access2000 MDB Siggy
