PHPmailer tutorial?


New member
So, currently using PHP mail() for simple emails. Now I need to send an attachment. In comes PHPmailer.
Are there any recent tutorials on how to install and configure PHPmailer without using Composer?
Most of the information I have googled is old.

I am running PHP 7.4 in my test environment. My production environment is PHP 8.1.2. Don't ask me why, but any concerns with this?
