php - 在要邮寄的表格上显示前导零

问题描述

我创建了一个将值插入数据库的表单，这些值也通过电子邮件发送。

这是问题所在：

首先，这是我的数据库架构：

数据库架构

如您所见，我有一个名为的列trackingcode，其属性为unsigned zerofill

001、002、003trackingcode等值也是如此......

问题是当它通过电子邮件发送时，它只读取整数，如 1、2、3 等等......

是否也可以在电子邮件上显示零？

这是发送到电子邮件的代码：

解决方案

也许你应该看看 sprintf [1]

$number = 2;
echo sprintf("%03d", $number); // 002
