How to extract text from word file .doc,docx,.xlsx,.pptx php
可能有一种情况，我们需要从Word文档中获取文本以供将来使用，以便在用户上传的文档中搜索字符串，例如在cv / resumes中进行搜索，并发生如何获取文本，打开和阅读的常见问题用户上传的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，并且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 .
class DocxConversion{

Document_file_format Doc 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.
Usage of above class
