key from the database specified with
dba.
keyThe key the data is specified by.

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().
dbaThe database handler, returned by dba_open() or dba_popen().
skipThe 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.

otherwise.

the 3rd argument is now deprecated.
