php实现将HTML页面转换成word并且保存的方法

前端之家收集整理的这篇文章主要介绍了php实现将HTML页面转换成word并且保存的方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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

标签和

    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。
