Design Pattern-Observer pattern

[Php]/* Consider the following scenarios: one wrong password, two wrong login attempts, five wrong verification codes, and 10 wrong verification codes. the general idea of locking the account is as follows: {if (error) {Times + 1} if (Times = 1) {} elseif (Times = 2) {} else...

/*
Consider the following scenarios:
The password is incorrect once, prompting you to log on again
Two errors. the verification code is displayed.
Five errors make the verification code more complex
10 errors, locked account
 
General Idea:
 
{
 
If (error ){
Times + 1
}
 
If (Times = 1 ){
} Else if (Times = 2 ){

This is obviously unreasonable.

Determining whether the user name/password is correct is a login type
Logon success/failure, rewards/punishments are rewards and punishments.
