There was a bug in all the recent MySQL and MariaDB packages that MySQL extension was getting added in PHP 7.3 binary after installing MySQL on server, which caused the following PHP startup error to be displayed:
PHP Warning: PHP Startup: Unable to load dynamic library 'mysql.so' (tried: /usr/local/apps/php73/ext/mysql.so (/usr/local/apps/php73/ext/mysql.so: cannot open shared object file: No such file or directory), /usr/local/apps/php73/ext/mysql.so.so (/usr/local/apps/php73/ext/mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

We have fixed this issue in the recent MariaDB and MySQL updated versions packages. We would request all our users to update the MySQL and MariaDB packages on their servers.

If you face any issues related to packages updation then let us know in the comments section. We will make sure to answer as many queries as we can.
