                  问题描述

                  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!
