title: Search through PDF files with PHP
body: <p>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.</p>
  
  <p>So, as naive as I am, i tried to simple get a stream using file_get_contents(), obviously it's an encrypted-like output ;)</p>
  
  <p>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.</p>
