Please tell me how can I check the IP if it makes 100500 requests per second and issue die () at the beginning of the page in php to protect against bulk requests and mini ddos ​​attacks? I am new to security matters. Help to get rid of hacking attempts.

Answer 2

If IP makes 100500 requests per second, then you can't check, the checker will die.

iptables, fail2ban,..
On php or nginx, you can make protection from F5 ))
