title: Symfony SQLite3 and PDO drivers
body: <p>I'm running Symfony but it doesn't find pdo drivers and the demo application throws exception of SQLite3 exceptions.<br>
  The configuration checkers says:</p>
  
  <blockquote>
    <p>PDO should have some drivers installed (currently available: none)
    Install PDO drivers (mandatory for Doctrine).</p>
  </blockquote>
  
  <p>But in php.ini I have:</p>
  
  <blockquote>
    <p>extension=php_pdo_mysql.dll<br>
    extension=php_pdo_sqlite.dll<br>
    extension=php_sqlite3.dll</p>
  </blockquote>
  
  <p>In the end, the symfony app says:</p>
  
  <pre><code>// Check if SQLite is enabled
          if ($isDriverException &amp;&amp; $this-&gt;isSQLitePlatform() &amp;&amp; !extension_loaded('sqlite3')) {
              $event-&gt;setException(new \Exception('PHP extension "sqlite3" must be enabled because, by default, the Symfony Demo application uses SQLite to store its information.'));
          }
  </code></pre>
  
  <p>But I knew that with PHP 5.3+ it's installed by default.<br>
  I'm running on windows with PHP7.1 installed</p>
