Querying

queryRaw

$buf = $dc->queryRaw($query_string);

Send a query string to the selected server and returns the raw result buffer. Implicitly close()s the connection.

queryRawNC

$buf = $dc->queryRawNC($query_string);

Send a query string to the selected server and returns the raw result buffer. No implicit close().

queryMulti

@bufs = $dc->queryMulti(@query_strings);

Sends a series of query strings or requests to the server, and returns a list of raw result buffers. Implicitly close()s the client after all requests have been sent, but not between individual requests.

query

$hits = $dc->query($query_string);

Send a query string to the selected server and parses the result into a list of hits.
