title: What is no-debug-non-zts-20090626?
body: <p>In <code>php.ini</code> I have:</p>
  
  <pre><code>extension_dir = "/usr/lib/php/extensions"
  </code></pre>
  
  <p>However, running <code>php-config</code> gives:</p>
  
  <pre><code>--extension-dir  [/usr/lib/php/extensions/no-debug-non-zts-20090626]
  </code></pre>
  
  <p>This directory does not exist, and I could not find any information about it on the Web.</p>
  
  <p>Can anyone shed some light on this strange directory?</p>
