Search through PDF files with PHP
提问by Ben Fransen
I'm trying to find a way to search inside PDF files. I came accross the PHP PDF class but I can't seem to find any function for reading/searching a filestream.
我正在尝试找到一种在 PDF 文件中进行搜索的方法。我遇到了 PHP PDF 类，但似乎找不到任何用于读取/搜索文件流的函数。
So, as naive as I am, i tried to simple get a stream using file_get_contents(), obviously it's an encrypted-like output ;)
因此，尽管我很天真，但我尝试使用 file_get_contents() 来简单地获取流，显然它是一个类似加密的输出；)
So my question, is there any way to search through PDF files? I'm looking for script-only / free / open source solutions and not buying some expensive commercial libraray.
所以我的问题是，有没有办法搜索PDF文件？我正在寻找纯脚本/免费/开源解决方案，而不是购买一些昂贵的商业图书馆。

There seems to be some code herethat could help - a simple class that reads a PDF into plaintext. Unsure if it supports decryption.
