file_get_contents or readfile for displaying filesystem image

Question

Can anyone advise on what is the best PHP function for displaying an image stored in a filesystem - file_get_contents or readfile. We are switching

Answer 1

I would do something like:

header('Content-type: image/jpeg');
readfile('something.jpg');

readfile() seems more useful for this purpose as it reads a file and writes it to the output buffer returning the number of bytes read from the file, or false on an error.
