here is a good example for this;



 $dbh = dba_open( "./data/products", "c", "gdbm" ) 

       or die( "Couldn't open database" );

 

 dba_insert( "Sonic Screwdriver", "23.20", $dbh);

 dba_insert( "Tricorder", "55.50", $dbh);

 dba_insert( "ORAC AI", "2200.50", $dbh);

 dba_insert( "HAL 2000", "4500.50", $dbh);

 

 dba_close( $dbh );
