php如何将html转成word

php将html转成word的方法：首先安装zip.dll压缩扩展；然后将规定好了的xml压缩成一个zip包；最后把后缀名改成doc或者docx即可。

php实现将HTML页面转换成word并且保存的方法

这里用使用到一个PHP的工具叫：PHPWord。

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

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。
