Question

Answer 1

Agree with other commentators. Protection must be implemented not in php, but by means of the server. However, if you are completely impatient, then you can do something a la vitalykim.ru/zashhita-ot-ddos-atak-na-php.html
And implement a call to check for ddos ​​in the MY_Controller constructor and inherit all controllers from it, or implement hook pre_controller .

Answer 2

nginx limit_req
at the php level is useless, because the php script is already running, but you just need to protect yourself from its frequent launch.

Answer 3

Another option: you can use fail2ban for iptables.
