在 PHP 中舍入到最大千、百等

2022-01-17 00:00:00 numbers rounding php

我有一个非常简单的 PHP 问题，但我不知道该怎么做.

I have a pretty simple PHP question but I'm not sure how to do that.

我想根据数据库返回的值四舍五入到最大百或千.

I want to round to the max hundred or thousand depending on the value returned by the database.

这里有几个我需要的例子:

Here are a few examples of what I need :

  • DB返回值11，我要PHP输出20
  • DB返回值104，我要PHP输出200
  • DB返回值1404，我要PHP输出2000
  • DB返回值10241，我要PHP输出11000

等等等等

我想根据传递的值创建一个自动函数来执行此操作.

I would like to create an automatic function to do that, according to the value passed.

谢谢！
