title: PHP output file on disk to browser
body: <p>I want to serve an existing file to the browser in PHP.
  I've seen examples about image/jpeg but that function seems to save a file to disk and you have to create a right sized image object first (or I just don't understand it :))</p>
  
  <p>In asp.net I do it by reading the file in a byte array and then call context.Response.BinaryWrite(bytearray), so I'm looking for something similar in PHP.</p>
