Wordファイルからテキストを抽出する方法.doc、docx、.xlsx、.pptx php
将来の使用のためにWord文書からテキストを取得する必要があるシナリオがあり、cv's/resumesでの検索のように、ユーザーがアップロードした文書内の文字列を検索し、ユーザーがWordドキュメントをアップロードした場合、いくつかの役立つリンクがありますが、問題全体を解決することはできません。アップロード時にテキストを取得し、データベースにテキストを保存する必要があり、データベース内で簡単に検索できます。
.doc/.docxに適切な仕事をする簡単なクラスは、 PHP docx reader：MS Word Docxファイルをtext 。

Docxドキュメントの場合、docx2txtツールの使用をお勧めします（少なくともDebian/Ubuntuで利用可能）：
docx2txt < your_file.docx
READMEは、vimと統合する方法を説明します。 .vimrcに追加します：
" use docx2txt.pl to allow VIm to view the text content of a .docx file directly.
autocmd BufReadPre *.docx set ro
autocmd BufReadPost *.docx %!docx2txt
（emacsと統合する方法も説明します）。
ハッカーのために、このツールはPerlで書かれています。
