Composer warning: Unable to load dynamic library 'php_mysql.dll'

HI! Typing “composer” in terminal I am getting these warnings. Any idea how to fix?

Warning: PHP Startup: Unable to load dynamic library ‘php_mysql.dll’ (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20180731/php_mysql.dll (/usr/local/lib/php/extensions/no-debug-non-zts-20180731/php_mysql.dll: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20180731/php_mysql.dll.so (/usr/local/lib/php/extensions/no-debug-non-zts-20180731/php_mysql.dll.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Can you explain exactly the steps to reproduce this error/warning (versions, configs, command, etc).
FYI: *.dll is a Windows thingy. All Docker containers run on Linux, so I have no clue what this error is about.

I fixed this error.
I had in php.ini ```

[PHP_MYSQL]
extension=php_mysql.dll
I removed it and is ok now.
thank you!
