title: sorting array by values A to AZ?
body: <p>OK so I have a head scratcher here. </p>
  
  <p>I have an array and it was all in a random order I have been able to use </p>
  
  <pre><code>array_multisort($sort['key2'], SORT_ASC, $sort['key3'],SORT_ASC,$myArray); 
  </code></pre>
  
  <p>Which has order <code>key['2']</code> alphabetically which is great, but the problem I have is I need it to be order A,B,C,D all the way to AB, AC, AD through to AZ </p>
  
  <p>Can any one give me an idea on how I would do this ??</p>
  
  <pre><code>25214,10,A,1
  30124,5,A,1
  15248,5,AB,10
  15248,10,AB,10
  52568,7,AB,10
  33331,6,AC,4
  36389,4,AC,5
  11224,8,AZ,4
  88958,4,AZ,10
  25636,1,C,8
  </code></pre>
  
  <p>I need it to order it like this </p>
  
  <pre><code>25214,10,A,1
  30124,5,A,1
  25636,1,C,8 &lt;--- this is the problem all singe letters need to go before the AB ect 
  15248,5,AB,10
  15248,10,AB,10
  52568,7,AB,10
  33331,6,AC,4
  36389,4,AC,5
  11224,8,AZ,4
