title: Return only unique values from foreach
body: <p>I'm currently trying to use a foreach to return all the addresses using the relation from my event model. All is fine, returns all the addresses but will return even the duplicate results. I tried the array_unique but not sure I have the syntax correct.</p>
  
  <pre><code>&lt;?php  
      foreach ($data-&gt;events as $address) {
          //array_unique($address, SORT_REGULAR);
          echo $address-&gt;getAddressString() ."&lt;br/&gt; &lt;br/&gt;";
      }
    ?&gt;
  </code></pre>
