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。
