title: Providing Options like Callback in get() in Couchbase PHP Client
body: <p>I am using <a href="https://github.com/couchbase/php-couchbase" rel="nofollow">PHP Client for couchbase </a></p>
  
  <pre><code>    $cluster = new CouchbaseCluster(127.0.0.1); 
      $bucket = $cluster-&gt;openBucket('default');
      $doc = $uds-&gt;get(array('key1','key2'));
  </code></pre>
  
  <p>In this case the this $doc is of type CouchbaseMetaDoc class. However I need to process each $doc fetched using a callback function.</p>
  
  <p>As per the old (1.2.0) <a href="http://www.couchbase.com/autodocs/couchbase-php-client-1.2.0/classes/Couchbase.html#method_get" rel="nofollow">API documentation</a> it only support missing objects but it is passed as one of the $options as an array in the new <a href="http://docs.couchbase.com/sdk-api/couchbase-php-client-2.1.0/classes/CouchbaseBucket.html" rel="nofollow">client version (2.1.0)</a></p>
