How to extract text from word file .doc,docx,.xlsx,.pptx php

提问by M Khalid Junaid

There may be a scenario we need to get the text from word documents for the future use to search the string in the document uploaded by user like for searching in cv's/resumes and occurs a common problem that how to get the text , Open and read a user uploaded Word document,there are some helpful links but don't cure the whole problem.We need to get the text at the time of uploading and save text in database and we can easily search within the database.

可能有一个场景我们需要从word文档中获取文本，以备日后使用来搜索用户上传的文档中的字符串，比如在简历/简历中搜索，并且出现一个常见的问题，如何获取文本，打开和阅读一个用户上传的Word文档，有一些有用的链接，但不能解决整个问题。我们需要在上传时获取文本并将文本保存在数据库中，我们可以在数据库中轻松搜索。

Here is a simple class which does the right job for .doc/.docx , PHP docx reader: Convert MS Word Docx files to text.

这是一个简单的类，它为 .doc/.docx 做正确的工作， PHP docx 阅读器：将 MS Word Docx 文件转换为文本。

Document_file_formatDoc files are binary blobs.They can be read by using fopen.While .docx files are just zip files and xml files xml files in a zipfile container (source wikipedia)you can read them by using zip_open.

Document_file_formatDoc 文件是二进制 blob。它们可以使用fopen读取。而 .docx 文件只是 zip 文件和 xml 文件zipfile 容器（源维基百科）中的 xml 文件，您可以使用zip_open读取它们。

Usage of above class

以上类的用法

$docObj = new DocxConversion("test.doc");
//$docObj = new DocxConversion("test.docx");
//$docObj = new DocxConversion("test.xlsx");
//$docObj = new DocxConversion("test.pptx");
echo $docText= $docObj->convertToText();

For docx documents, I suggest use of docx2txttool (available at least on Debian/Ubuntu):

对于 docx 文档，我建议使用docx2txt工具（至少在 Debian/Ubuntu 上可用）：

docx2txt < your_file.docx

READMEexplain how to integrate it with vim. Add to your .vimrc:

README解释如何将它与 vim 集成。添加到您的.vimrc：

" use docx2txt.pl to allow VIm to view the text content of a .docx file directly.

(it also explain how to integrate with emacs).
