title: Strange value set as a key in the array in cakephp2
body: <p>I have the problem with the following code. The query sent was normal, just fetching all the data I need. However, When I print_r the $data, the all the datas from find('all')  are not contained in [MYDATA] but also set in an unknown ['c'] and ['a'] array. Has anyone encounter this kind of weird problem ? Some examples or hint would be great. I would love to hear from you!</p>
  
  <pre><code> $data = $this-&gt;MYDATA-&gt;find(
              'all',
              array(
                  'conditions' =&gt;
                      array(
                          array('my_id' =&gt; $var['id']),
  
                      ),
                  'order' =&gt;array('my_name'=&gt;'DESC')
          ));
  </code></pre>
  
  <p>The following is the result from $data when using the 'my_name'=>'DESC' condition.</p>
  
  <pre><code>[0] =&gt; Array
      (
          [MYDATA] =&gt; Array
              (
                  [id] =&gt; 79
                  [my_birth_day] =&gt; 1990-06-20
                  [my_address] =&gt; 400
                  [my_age] =&gt; 26
                  [my_name] =&gt; Joy
                  [my_id] =&gt; 1
                  [created] =&gt; 2017-06-19 15:39:44
              )
  
          [c] =&gt; Array
              (
                  [my_test] =&gt; math
              )
  
          [a] =&gt; Array
              (
                  [my_date] =&gt; 2017-08-13
              )
  
      )
  </code></pre>
  
  <p>Without using the'my_name'=>'DESC' condition. This is the correct array. I want it to have the values return like this.</p>
  
  <pre><code>    [0] =&gt; Array
      (
          [mydata] =&gt; Array
              (
                  [id] =&gt; 79
                  [my_birth_day] =&gt; 1990-06-20
                  [my_address] =&gt; 400
                  [my_age] =&gt; 26
                  [my_name] =&gt; Joy
                  [my_id] =&gt; 1
                  [my_test] =&gt; math
                  [created] =&gt; 2017-06-19 15:39:44
                  [my_date] =&gt; 2017-08-13
              )
  </code></pre>
