Hi all ... I am an absolute newbie to php ... Here i am looking at wririting a script in php which can do a search in my berkley db 3.0.11 database and retrieve the required information ... In order to do the same which set of functions are supported .. is it that the functions mentioned with dbm like dbmopen etc do the trick ... Any guidance will be appreciated ... Thanks and regards Sovan
