title: Zend DB fetchAll(): where as array
body: <p>I'm confused as to why Zend_DB doesn't accept an array of <code>WHERE</code> clauses - or am I incorrect? I have made the following work around:</p>
  
  <pre><code>$all = new ORM_Model_DbTable_Asset();
  $wheres = array('id &gt; 0', 'enabled' =&gt; 1);
  $all = $all-&gt;fetchAll(implode(' AND ', $wheres))-&gt;toArray();
  </code></pre>
  
  <p>for what I hoped would be:</p>
  
  <pre><code>$all = new ORM_Model_DbTable_Asset();
  $wheres = array('id &gt; 0', 'enabled' =&gt; 1);
  $all = $all-&gt;fetchAll($wheres)-&gt;toArray();
  </code></pre>
  
  <p>Slightly disappointing, am I missing something?</p>
