test.php

<?php
namespace dark9\cli;
$couchbase = new \Couchbase\Cluster('0.0.0.0?dnssrv=false');
$bucket = $couchbase->openBucket();
$bucket->queueSize('abc'); // abc does not exist data.

queueExists method same problem.

Thank you for issue report, it has been fixed in http://review.couchbase.org/77174

Thank you for fixed.

btw: now queueAdd does not thrown exception, don’t know if it fails.
