Turn an array into an bidimensional array and remove the first 11 entries
<p>I have been trying to figure this out until my brain imploded.
Im trying to sort an array.</p>

<p>The first 11 entries has to be removed, then the next 7 entries has to be placed in an new array and then the next 7 entries and so on. Until there is no more entries.</p>

<p>Short example:</p>

<p><strong>Turn this:</strong> </p>

<pre><code>Array (
     [0] =&gt; 0
     [1] =&gt; 1
     [2] =&gt; 2
     [3] =&gt; 3
     [4] =&gt; 4
     [5] =&gt; 5
     [6] =&gt; 6
     [7] =&gt; 7
     [8] =&gt; 8
     [9] =&gt; 9
     [10] =&gt; 10
     [11] =&gt; 11
     [12] =&gt; 12
     [13] =&gt; 13
     [14] =&gt; 14
     [15] =&gt; 15
     [16] =&gt; 16
     [17] =&gt; 17
     [18] =&gt; 18
)
</code></pre>

<p><strong>Into this:</strong></p>

<pre><code>Array (
     [0] =&gt; Array (
               [0] =&gt; 11
               [1] =&gt; 12
               [2] =&gt; 13
               [3] =&gt; 14
               [4] =&gt; 15
               [5] =&gt; 16
               [6] =&gt; 17
            )
)
</code></pre>
