I&#39;m trying to output lists of objects as json and would like to know if there&#39;s a way to make objects usable to `json_encode`?  The code I&#39;ve got looks something like

    $related = $user-&gt;getRelatedUsers();
    echo json_encode($related);

Right now, I&#39;m just iterating through the array of users and individually exporting them into arrays for `json_encode` to turn into usable json for me.  I&#39;ve already tried making the objects iterable, but `json_encode` just seems to skip them anyway.

_edit_: here&#39;s the var_dump();

    php &gt; var_dump($a);
    object(RedBean_OODBBean)#14 (2) {
      [&quot;properties&quot;:&quot;RedBean_OODBBean&quot;:private]=&gt;
      array(11) {
        [&quot;id&quot;]=&gt;
        string(5) &quot;17972&quot;
        [&quot;pk_UniversalID&quot;]=&gt;
        string(5) &quot;18830&quot;
        [&quot;UniversalIdentity&quot;]=&gt;
        string(1) &quot;1&quot;
        [&quot;UniversalUserName&quot;]=&gt;
        string(9) &quot;showforce&quot;
        [&quot;UniversalPassword&quot;]=&gt;
        string(32) &quot;&quot;
        [&quot;UniversalDomain&quot;]=&gt;
        string(1) &quot;0&quot;
        [&quot;UniversalCrunchBase&quot;]=&gt;
        string(1) &quot;0&quot;
        [&quot;isApproved&quot;]=&gt;
        string(1) &quot;0&quot;
        [&quot;accountHash&quot;]=&gt;
        string(32) &quot;&quot;
        [&quot;CurrentEvent&quot;]=&gt;
        string(4) &quot;1204&quot;
        [&quot;userType&quot;]=&gt;
        string(7) &quot;company&quot;
      }
      [&quot;__info&quot;:&quot;RedBean_OODBBean&quot;:private]=&gt;
      array(4) {
        [&quot;type&quot;]=&gt;
        string(4) &quot;user&quot;
        [&quot;sys&quot;]=&gt;
        array(1) {
          [&quot;idfield&quot;]=&gt;
          string(2) &quot;id&quot;
        }
        [&quot;tainted&quot;]=&gt;
        bool(false)
        [&quot;model&quot;]=&gt;
        object(Model_User)#16 (1) {
          [&quot;bean&quot;:protected]=&gt;
          *RECURSION*
        }
      }
    }

and here&#39;s what json_encode gives me:

    php &gt; echo json_encode($a);
    {}
I ended up with just this:

        function json_encode_objs($item){   
            if(!is_array($item) &amp;&amp; !is_object($item)){   
                return json_encode($item);   
            }else{   
                $pieces = array();   
                foreach($item as $k=&gt;$v){   
                    $pieces[] = &quot;\&quot;$k\&quot;:&quot;.json_encode_objs($v);   
                }   
                return &#39;{&#39;.implode(&#39;,&#39;,$pieces).&#39;}&#39;;   
            }   
        }   


It takes arrays full of those objects or just single instances and turns them into json - I use it instead of json_encode.  I&#39;m sure there are places I could make it better, but I was hoping that json_encode would be able to detect when to iterate through an object based on its exposed interfaces.
