title: natsort() not sorting alphabetically case insensitively in PHP
body: <p>So I have 2 questions:</p>
  
  <blockquote>
    <ol>
    <li>from what I understand natsort() is supposed to sort an array alphabetically case insensitively but once I compile the code below.</li>
    </ol>
  </blockquote>
  
  <pre><code>&lt;?php
          function splitSort($sentence){
              $stringArray = explode(" ",$sentence);
              natsort($stringArray);
              for($i=0; $i&lt;count($stringArray);$i++){
                  echo $stringArray[$i] . ", ";
              }
          }
          splitSort("Hellod darkness hello My old");
  ?&gt;
  </code></pre>
  
  <p>I get </p>
  
  <blockquote>
    <p>Hellod, darkness, hello, My, old,</p>
  </blockquote>
  
  <p>where i thought I was supposed to get</p>
  
  <blockquote>
    <p>darkness, hello, Hellod, My, old</p>
  </blockquote>
  
  <ol start="2">
  <li>If the sorting was truly case insensitive and the expected result would occur if I change Hellod to Hello which hello would come first?</li>
  </ol>
