The essence of judging whether a number is odd or even is to judge whether the number can be divisible by 2:

If it is divisible by 2, it is even.

In PHP, the remainder operator "%" can be used to determine whether to divide or not.

If a number is divided by 2 and there is no remainder (0), then it is divisible by 2, which is an even number.

If a number is divided by 2 and there is a remainder (not 0), then it is not divisible by 2, which is odd.
