MONGOCURSOR.GETREADPREFERENCE(3) 1 MONGOCURSOR.GETREADPREFERENCE(3)MongoCursor::getReadPreference - Get the read preference for this query
SYNOPSIS
public array MongoCursor::getReadPreference (void )
DESCRIPTION PARAMETERS
This function has no parameters.
RETURN VALUES
This function returns an array describing the read preference. The array contains the values type for the string read preference mode (cor-
responding 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.
EXAMPLES
Example #1

<?php
$m = new MongoClient();
$cursor = $m->test->users->find();
$cursor->setReadPreference(MongoClient::RP_SECONDARY, array(
array('dc' => 'east', 'use' => 'reporting'),
array('dc' => 'west'),
array(),
));
var_dump($cursor->getReadPreference());
?>
The above example will output:
array(2) {
["type"]=>
string(9) "secondary"
["tagsets"]=>
array(3) {
[0]=>
array(2) {
["dc"]=>
string(4) "east"
["use"]=>
string(9) "reporting"
}
[1]=>
array(1) {
["dc"]=>
string(7) "west"
}

}
}
