title: Php extension not loaded
body: <p>Using a  .user.ini file with <code>extension=geoip.so</code> (or mysqli.so) I'm trying unsuccessfully to load the relevant module: in the phpinfo() page of Php 7.1 (or even Php5.4) the module is never shown.</p>
  
  <p>1) The .user.ini file is working correctly because I'm able to modify the variable memory_limit.</p>
  
  <p>2) The phpinfo() function correctly shows the extension_dir folder containing .so extensions that I want to load (in the php.ini file this variable is not present, however).</p>
  
  <p>3) The php error log contains no message.</p>
  
  <p>Every suggestion is welcome.</p>
