如何在php中提取数字的最后两位数字?

[英]How to extract the last two digits of a number in php?

I have this number 12455, I want to extract the last two digits like $result = 55 .我有这个数字 12455,我想提取最后两位数字,如 $result = 55 。

I tried :我试过 :

$order_id = 12455;
$lastTwoNumbers = $order_id[strlen($order_id)-2];

您可以使用以下代码:

$lastTwoNumbers = substr($order_id, -2);

You can use substr() to get the last two chars of that string (use a negative " start " parameter to count from the end):您可以使用substr()获取该字符串的最后两个字符(使用负的“ start ”参数从末尾开始计数):

<?php

$order_id = 12455;
$lastTwoNumbers = (int) substr($order_id, -2);
echo $lastTwoNumbers;

Will return 55. (The result will be of type string, (int) makes sure it will be integer after)将返回 55。(结果将是字符串类型, (int)确保它之后是整数)
