title: php shuffle() returns one item
body: <p>Anyone have any idea why shuffle() would only return 1 item? </p>
  
  <p>when using:</p>
  
  <pre><code>$array2 = shuffle($array1);
  </code></pre>
  
  <p>with the following array($array1):</p>
  
  <pre><code>Array
  (
      [0] =&gt; 1
      [1] =&gt; 5
      [2] =&gt; 6
      [3] =&gt; 7
      [4] =&gt; 8
      [5] =&gt; 10
      [6] =&gt; 11
      [7] =&gt; 12
      [8] =&gt; 13
      [9] =&gt; 14
  )
  </code></pre>
  
  <p>The output of:</p>
  
  <pre><code>print_r($array2);
  </code></pre>
  
  <p>is simply: <strong>1</strong></p>
  
  <p>Any idea as to why it would not only not shuffle the array, but knock off the remaining 9 items in the array?</p>
  
  <p>thanks!</p>
