Ubuntu 18.04 + PHP7.3 - Unable to load dynamic library 'pdo_mysql.so'. How to solve it?

  • 772

I have updated my SO form Ubuntu 16.04 to 18.04. I am using NGINX as a server and updated my php from 7.1 to 7.2 and 7.3.

Now when I do php -v this is what I get:

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql.so' (tried: /usr/lib/php/20180731/pdo_mysql.so (/usr/lib/php/20180731/pdo_mysql.so: undefined symbol: pdo_parse_params), /usr/lib/php/20180731/pdo_mysql.so.so (/usr/lib/php/20180731/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

This is a warning but I can't load for example the php Artisan. This is what happens:

$ php artisan
PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql.so' (tried: /usr/lib/php/20180731/pdo_mysql.so (/usr/lib/php/20180731/pdo_mysql.so: undefined symbol: pdo_parse_params), /usr/lib/php/20180731/pdo_mysql.so.so (/usr/lib/php/20180731/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

In Connection.php line 1262:

Class 'PDO' not found

Inside the file /usr/lib/php/20180731 I have the pdo_mysql.so.
