title: Can PHP's glob() be made to find files in a case insensitive manner?
body: <p>I want all CSV files in a directory, so I use</p>
  
  <pre><code>glob('my/dir/*.CSV')
  </code></pre>
  
  <p>This however doesn't find files with a lowercase CSV extension.</p>
  
  <p>I <em>could</em> use </p>
  
  <pre><code>glob('my/dir/*.{CSV,csv}', GLOB_BRACE);
  </code></pre>
  
  <p>But is there a way to allow all mixed case versions? Or is this just a limitation of <code>glob()</code> ?</p>
