Php生成Excel文件如此简单

前阵子做了一个调查的小小项目。客户的想法是通过后台能将收集到的资料导出到Excel文件中，这样方便阅读，方便保存，及提取信息。

于是我就开始动手了:-)，分析了一下这个小小项目，对于我来说最大的难点就是生成Excel文件。本人只是一个小小站长。生成Excel文件之前也没搞过。当时只知道这么一点点：先用php header()出一个Excel头,然后后面跟上Excel的XML代码，这样就能导出Excel功能了。但是Excel头是什么? Excel的XML写法又如何写呢?一直不明！

于是又开始我的g.cn之旅……最终功夫不负有心人，被我找到了一个外国老大写的程序，原名为：class-excel-xml.inc.php。我在未争得此牛人同意的情况下做了如下修改，于是我的那个小小项目不到一天完工，客户也比较满意，毕竟他要求的功能咱实现了！

如您也对生成Excel而烦恼，可以看一下此段代码：
