一个 php 动态生成组织结构图的类，比如我们公司的组织结构，总栽，总经理，IT部，客服部，业务部，这就属于一个组织结构，还有类似于这样的其它组织，利用这个 PHP 的类对象可以很好的生成一个组织机构的图形，更形象的进行展出出来，让大家一眼可以看出公司的一个组织人员状态。

这个类其实用得还不是很多，比如像企业站，我们基本上就可以直接用 PS 来画一个组织机构图了，那么对于 PHP 动态生成组织结构图，应该用在什么地方呢，我想可以放在一些比较大型的信息站上面，就像 B2B 类的网站，每个企业会员都有自己的公司黄页，如果要加企业的组织结构图，就可以用这个 php 动态生成组织结构类，每个单位的组织结构图都不一样，可以进行调用不同的参数生成不同的组织结构图，这也是 php 功能强大的体现之一。
