MongoClient::getReadPreference — Get the read preference for this connection
This extension that defines this method is deprecated. Instead, the MongoDB extension should be used. There is no equivalent for this method in the new extension.
Bu işlevin değiştirgesi yoktur.
This function returns an array describing the read preference. The array contains the values type
for the string read preference mode (corresponding to the MongoClient constants), and tagsets
containing a list of all tag set criteria. If no tag sets were specified, tagsets
will not be present in the array.

The return value has changed to be consistent with
MongoClient::setReadPreference(). The
type value was changed from a number to a string,
type_string was removed, and
tagsets now expresses tags as key/value pairs instead
of colon-delimited strings.
