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.

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{
private $filename;
public function __construct($filePath) {
$this->filename = $filePath;
}
private function read_doc() {
$fileHandle = fopen($this->filename, "r");
$line = @fread($fileHandle, filesize($this->filename));
$lines = explode(chr(0x0D),$line);
$outtext = "";
foreach($lines as $thisline)
{
$pos = strpos($thisline, chr(0x00));
if (($pos !== FALSE)||(strlen($thisline)==0))
{
} else {
$outtext .= $thisline." ";
}
}
$outtext = preg_replace("/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/","",$outtext);
return $outtext;
}

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
$docObj = new DocxConversion("test.doc");
//$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 docx2txt tool (available at least on Debian/Ubuntu):
docx2txt < your_file.docx
README explain how to integrate it with vim. Add to your .vimrc:
" 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
(it also explain how to integrate with emacs).
For hackers, this tool is written in perl.
