The way PHP judges that three digits are palindromes
This article introduces the way that PHP judges three digits as palindromes. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.
Thoughts:
1. The numbers on the three digits, ten digits and hundred digits can be taken out separately, that is, g, s, b.
2. Then add gears 100, slots 10 and hundred digits b.
This will result in a new three-digit hws.
3. Use the if statement to determine whether I is equal to hws, and you can judge whether the three-digit I is a palindrome number.
