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(), dba_replace() and dba_key_split().
Note: The skip parameter is available since PHP 4.3 to support cdb's capability of multiple keys having the same name.
Note: 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().
