Accessing a Berkeley DB V1.85 using PHP V4.0.5

Hello I am trying to access a Berkeley database V1.85 using PHP V4.0.5 (on Windows 2000) without success. I have tried the dbmopen() routines and dba_open(..., ..., "dbm") routines. dbmopen() etc. are successful but the results suggest that they do not support this database format. The dba_open() routine returns 'Warning: no such handler: dbm in "dba.php" on line 26'. php_db.dll and php_dba.dll are dynamically loaded. 1) Is DB1 another name for Berkeley DB 1.x? 2) Which database routines do I need to use? 3) Alternatively, can I use mysql V3.23 to manage the berkeley DB? I did not find any useful information in this regard. 4) I wish to avoid converting the database format if at all possible. 5) The database is a Redhat Source Navigator project. Any help offered would be greatly appreciated. Regards David Robinson (david-work@robinson-au.net)
