title: Fatal error: Class 'IntlCalendar' not found
body: <p>I'm trying to run the code that can be found there : </p>
  
  <p><a href="http://php.net/manual/en/intlcalendar.createinstance.php" rel="nofollow">http://php.net/manual/en/intlcalendar.createinstance.php</a></p>
  
  <p>for example</p>
  
  <p>and I'm getting the following error :</p>
  
  <pre><code>Fatal error: Class 'IntlCalendar' not found
  </code></pre>
  
  <p>My server is running </p>
  
  <pre><code>Linux sd-43596 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux
  </code></pre>
  
  <p><code>php --version</code> gives me :</p>
  
  <pre><code>PHP 5.4.39-0+deb7u2 (cli) (built: Mar 25 2015 08:33:29)
  Copyright (c) 1997-2014 The PHP Group

  </code></pre>
  
  <p>and <code>php -m</code> :</p>
  
  <pre><code>...
  intl
  ...
  </code></pre>
  
  <p>among other modules of course...</p>
  
  <p>and <code>apache2 -v</code> :</p>
  
  <pre><code>Server version: Apache/2.2.22 (Debian)
  Server built:   Dec 23 2014 22:48:29
  </code></pre>
  
  <p>to finish, it seems the module is enabled, as there's a <code>intl.ini</code> file in the <code>/etc/php5/mods-available directory</code></p>
  
  <p>I don't know if I'm doing wrong, I can't get php intlCalendar class working at all ...</p>
  
  <p>Please do I have basic tests/verifications to perform in order to fix it ?</p>
