title: phpmyadmin CoreExtension.php#1608array_key_exists(): Using array_key_exists() on objects is deprecated
body: <p>I have problem with twig. i installed phpmyadmin through apt and it depends on php-twig that seems old. currently the newest version of twig is <code>3.2.1</code> and for one in apt repo is <code>2.10.0-2</code> (i don't know if they are not compatible versions).</p>
  <p>Anyway i saw this error on phpmyadmin:</p>
  <p><code>phpmyadmin in ./../../php/Twig/Extension/CoreExtension.php#1608array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead</code>.</p>
