php實現將HTML頁面轉換成word並且保存的方法,phpword


本文實例講述了php實現將HTML頁面轉換成word並且保存的方法。分享給大家供大家參考,具體如下:

這裡用使用到一個PHP的工具叫:PHPWord。

生成Word的原理是,將堆規定好了的xml壓縮成一個zip包,並且把後綴名改成doc或者docx即可。

所以使用PHPWord,需要你的PHP環境安裝zip.dll壓縮擴展,我寫了一個demo.

功能說明:

20150507 — HTML中的<p>標簽和<ol>列表標簽的獲取
20150508 — 新增獲取文章中的圖片功能
20150509 — 新增行間距,並且過濾一下錯誤圖片
20150514 — 新增表格處理,並且將代碼改成面向對象
20150519 — 新增GD庫處理網絡圖片

上面的代碼重點感覺不是word生成,而是Simplehtmldom的使用,這是一個開源的HTML解析器,之前有提到,這幾天在看他的代碼,

引出了兩個學習方向

① 正在表達式

② 這個擴展的函數整理

看源代碼的收獲:

PHP的異常是可以捕獲的,而且PHP的錯誤也是可以捕獲的。

error_get_last() //用這個函數可以捕獲頁面中的PHP錯誤,不謝。
