本文实例讲述了php实现将html页面转换成word并且保存的方法。分享给大家供大家参考，具体如下：
这里用使用到一个php的工具叫：。
生成word的原理是，将堆规定好了的xml压缩成一个zip包，并且把后缀名改成doc或者docx即可。
所以使用phpword，需要你的php环境安装zip.dll压缩扩展，我写了一个demo.
功能说明：
20150507 — html中的<p>标签和<ol>列表标签的获取
20150508 — 新增获取文章中的图片功能
20150509 — 新增行间距，并且过滤一下错误图片
20150514 — 新增表格处理，并且将代码改成面向对象
20150519 — 新增gd库处理网络图片
我要评论

上面的代码重点感觉不是word生成，而是simplehtmldom的使用，这是一个开源的html解析器，之前有提到，这几天在看他的代码，
引出了两个学习方向
① 正在表达式
② 这个扩展的函数整理
看源代码的收获：
php的异常是可以捕获的，而且php的错误也是可以捕获的。
error_get_last() //用这个函数可以捕获页面中的php错误，不谢。
