在多个Word文档文件中查找单独的文本 [英] Find sepecific text in multiple word document files

问题描述

我想构建一个搜索模块，其中用户输入文本，并且该文本应搜索特定目录中的所有文件.我已经使用了这段代码:

I want to build a search module in which user enter a text and that text should search all files in particular directory. I have used this code :

$path_to_check = 'E:/xampp/htdocs/talent_orbit/test/';
$needle = 'test';

foreach(glob($path_to_check.'*.txt') as $filename)
{
   //print_r(file($filename));
  foreach(file($filename) as $fli=>$fl)
  {
      echo $f1;
    if(strpos($fl, $needle)!==false)
    {
      echo $filename.' on line '.($fli+1).': '.$fl;
    }
  }
}

但是它仅适用于.txt文件，应该在.doc文件中进行搜索.我也将 glob($ path_to_check.'*.txt')作为$ filename)更改为 glob($ path_to_check.'*.doc')作为$ filename)它不显示结果.请帮助我.

But it works only for .txt file, it should search in .doc file. I have also change glob($path_to_check.'*.txt') as $filename) to glob($path_to_check.'*.doc') as $filename) but it does not show the result. Please help me in this.

我还尝试了此

php > exec("egrep -rl 'string of what I want to find' full-or-relative-directory", $output);
php > print_r($output);
Array
(
  [0] => full-or-relative-directory/foo/bar.xml
)
php > $contents = file_get_contents($output[0]);

它显示Array()，我不知道在完整或相对目录"之间放置什么，我是指路径.

It shows Array(),I dont know what to put between "full-or-relative-directory" I mean the path.

我的代码:-

php > exec("egrep -rl 'rakesh' E:/xampp/htdocs/talent_orbit/test/", $output);
php > print_r($output);

如果不可能，我可以将doc文件转换为txt文件，然后在该txt文件中进行搜索吗?

谢谢.

推荐答案

这是不可能的.文档文件不是"纯文本"文件.尝试在编辑器中打开它，您会看到.搜索 *.txt 和 *.xml 文件将是可行的，因为它们基本上都是纯文本文件.一个doc文件中包含二进制数据.

This is not possible. A doc file isn't a 'plain text' file. Try opening it in your editor and you will see. Searching through *.txt and *.xml files will work, because those are basically all plaintext files. A doc file has binary data in it.

一种解决方案将是PHP的文档解析器(例如这一个)，但是它将需要一个遍历文件的脚本，使用解析器打开每个文件并搜索字符串.

A solution would be a doc-parser for PHP (for example this one), but it will require a script that loops through the files, open each and every file with the parser and search for the string.
