用PHP写的图片标注的小工具

最近需要做对图片进行进行标注审核的工作，为了方便展示图片并记录图片的标注结果，决定基于PHP和Mysql做一个简单的图片标注的页面。

在工作开始之前，需要先在自己的机器上搭建一个Apache+PHP+Mysql的开发环境，在网上有许多安装教程可以参考。

不过，如果想更加简便快捷的使用PHP/Mysql，在Windows下可以安装wamp5，MAC下可以安装Mamp，这两个软件已经集成了Apache+PHP+Mysql，安装很方便。

下面是整理的代码，主要功能如下：

从数据库读取图片信息

在一个页面显示多张图片

每次提交只影响一张图片的标注结果

显示每张图片的标注状态

可以随时更新图片的标注结果

这个小工具功能比较简单，不能一次写入多张图片的标注内容。
