title: rearrange array keys php
body: <p>i have this array:</p>
  
  <pre><code>Array
  (
  [15] =&gt;     13.1
  
  [16] =&gt;     Mark one answer
  
  [19] =&gt; You see a car on the hard shoulder of a motorway with a HELP pennant displayed. This means the driver is most likely to be
  
  [20] =&gt; a disabled person first aid trained
  
  [21] =&gt; a foreign visitor
  
  [22] =&gt; a rescue patrol person
  
  [25] =&gt; DES s15, HC r278);
  </code></pre>
  
  <p>How do i get it to sort the keys from 0?
  to get this: i know there is a function, but my head is burned, the sort function doesn't fit my needs since they rearrange values, and  i need them to be conserved.</p>
