dba_fetch() fetches the data
specified by key from the
database specified with
handle.
Key is the key the
data is specified by.
Skip is 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 is a database
handle returned by dba_open().
dba_fetch() returns the
associated string or FALSE,
if the key/data pair is found or not found, respectively.
See also: dba_exists(),
dba_delete(), dba_insert(), and
dba_replace().
注: The skip parameter is available since PHP 4.3 to support cdb's capability of multiple keys having the same name.
