title: findAllByAttributes not returning any value in Yii Framework
body: <p>I am passing following array in findAllByAttributes() method in my Yii Web App.</p>
  
  <pre><code>$fileArr= Array
  (
      [0] =&gt; 790c83
      [1] =&gt; 402faf
      [2] =&gt; 646209
      [3] =&gt; 9332c5
  )
  
  $files = File::model()-&gt;findAllByAttributes(array('code' =&gt; $fileArr));
          print_r($fileArr);
          exit;
  </code></pre>
  
  <p>and when I am trying to print this its returning blank. I also tried by converting an array into string by using implode function and passed it into <code>findAllByAttributes()</code> method but still its not working. How can I achieve this in yii?</p>
