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

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

    require_once 'PHPWord.php';
    require_once 'SimpleHtmlDom.class.php';

    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。
