title: PHP file searching
body: <p>i need to do a file search with php, and i have the filename search down, with glob, but i still need to search inside files.</p>
  
  <p>i have a prototype, at <a href="http://tann98.vacau.com/file-search" rel="nofollow noreferrer">tann98.vacau.com/file-search</a>, but i need keywords, and suggestions. plus it needs to look inside files to find matches.</p>
  
  <p>does anyone have ideas on how to do this kinda thing?  </p>
