title: PHP switch/case statement with case-insensitive string comparison
body: <p>Switch/case string comparison is case-sensitive.</p>
  
  <pre><code>&lt;?php
  $smart = "crikey";
  
  switch ($smart) {
       case "Crikey":
           echo "Crikey";
           break;
       case "Hund":
           echo "Hund";
           break;
       case "Kat":
           echo "Kat";
           break;
       default:
           echo "Alt Andet";
  }
  ?&gt;
  </code></pre>
  
  <p>Above code prints "Alt Andet", but I would like to compare strings case-insensitively and print "Crikey". How can I do that?</p>
