title: PDO drivers missing on Ubuntu 16.04 with PHP 7.2.4
body: <p>I wanted to try the latest version of PHP on Kubuntu 16.04, since then, it seems I can't use pdo with mysql.</p>
  
  <p>When I launch php, I have the following warning:</p>
  
  <pre><code>PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql' (tried: /usr/lib/php/20170718/pdo_mysql (/usr/lib/php/20170718/pdo_mysql: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/pdo_mysql.so (/usr/lib/php/20170718/pdo_mysql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0
  </code></pre>
  
  <p>I'm running </p>
  
  <pre><code>PHP 7.2.4-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Apr  5 2018 08:53:57) ( NTS )
  </code></pre>
  
  <p>I tried to fix with this solution : <a href="https://askubuntu.com/a/824505">https://askubuntu.com/a/824505</a>, but I've the same problem.</p>
  
  <p>However, in the phpinfo, there's a driver found for PDO (mysql).
  When I check a php -m, PDO and pdo_mysql are found.</p>
  
  <p>In the <strong>/usr/lib/php/20170718</strong> and <strong>/usr/lib/php/20151012</strong> folder, there is a pdo_mysql.so.</p>
  
  <p>I don't really know what else to try. Thanks in advance for your help.</p>
