title: PHP startup issue on Ubuntu 18.04
body: <p>I'm running Ubuntu 18.04 with Apache and PHP 7.2. Everything works fine. My queries are working fine, but now and then I get error report with following description </p>
  
  <pre><code>PHP Startup: Unable to load dynamic library 'mysqli' (tried: /usr/lib/php/20170718/mysqli (/usr/lib/php/20170718/mysqli: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/mysqli.so (/usr/lib/php/20170718/mysqli.so: undefined symbol: mysqlnd_global_stats))
  </code></pre>
  
  <p>I tried to search for it in php.ini but I can't find the problem. I tried to google it, but I can't find the same problem.</p>
  
  <p>Does anyone have any idea what is causing it and how can I stop it?</p>
