Ok guys I use this code for avoid hotlinking:

<?php 
    <img width="150" height="42" src='data:image/png;base64,echo base64_encode(file_get_contents("/USER/images/logo.png"))'>;
?>

This code works just fine, and since I include it in all of my page it cause a problem since the file_get_contents() sent an header, and I can't sent for example another header in the same page (Where this code is included), for example for do a redirect, how can I fix this problem? This code come from: Using PHP function include() to include a png image

Note that /USER/images/logo.png is a file that isn't in the root!

You can create a simple function that do the redirect for example and when you need to use it just call the function, in this way the double headers already sent message is gone – Sigma Sep 08 '18 at 09:22
How does a base64 encoded logo prevent hot linking? And why should one want to prevent that? – arkascha Sep 08 '18 at 09:24

`file_get_contents()` does _not_ send a header, by the way. – arkascha Sep 08 '18 at 09:25
@arkascha The logo isn't in the root, the file_Get_Contents() get this file from a non root folder – user9698140 Sep 08 '18 at 12:51
And what difference does that make? – arkascha Sep 08 '18 at 14:40
