  Problem 1

  To enable extensions, verify that they are enabled in your .ini files:
    - 
    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
    - /usr/local/etc/php/conf.d/tzone.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
