How to convert HTML page to word using php and save it

This article mainly introduces the method of converting HTML pages into word and saving them in PHP. It analyzes the functions and usage of the PHPWord tool in the form of examples. It has certain reference value. Friends in need can refer to it

The example in this article describes how PHP converts HTML pages into word and saves them. Share it with everyone for your reference, the details are as follows:

A PHP tool is used here called: PHPWord.

The principle of generating Word is to compress the specified xml into a zip package and change the suffix name to doc or docx.

So to use PHPWord, you need to install the zip.dll compression extension in your PHP environment. I wrote a demo.

20150507 — Obtaining e388a4556c0f65e1904146cc1a846bee tags and c34106e0b4e09414b63b2ea253ff83d6 list tags in HTML
20150508 — Added the function of getting pictures in articles
20150509 — Added line spacing and filtered wrong pictures
20150514 — Added table processing and changed the code to object-oriented
20150519 — Added GD library to process network images

The key point of the above code does not seem to be word generation, but the use of Simplehtmldom, which is an open source HTML parser. As mentioned before, I have been looking at his code these days, and

has led to two learning directions

① Expressing

② This extended function is organized

Reaping insights from the source code:

PHP exceptions can be caught, and PHP errors can also be caught .

error_get_last() //用这个函数可以捕获页面中的PHP错误，不谢。

Summary: The above is the entire content of this article, I hope it will be helpful to everyone's study.
