When working with inifiles this function accepts arrays as keys where index 0 is the group and index 1 is the value name. See: dba_key_split().
skip: The number of key-value pairs to ignore when using cdb databases. This value is ignored for all other databases which do not support multiple keys with the same name.
handle: The database handler, returned by dba_open() or dba_popen().

Returns the associated string if the key/data pair is found, FALSE otherwise.
