PHP: Execute bash script to start Chromium Browser

Question

I have the following bash script:

#!/bin/bash
export DISPLAY=:0.0
chromium-browser --incognito --kiosk https://www.google.de/

If I run it from terminal ./start_chromium.sh Chromium opens as expected.

Now I want to run this script using exec() in a PHP-file:

<?php
   exec('/home/pi/start_chromium.sh');
?>

Unfortunately nothing happens.

Checking the error log of Apache2, I see the following error message:

(chromium-browser-v7:1992): Gtk-WARNING **: 09:33:27.850: cannot open display: :0.0

Can anybody help me?

Thanks in advance. Regards Lars

This may be an Xauth issue. To test, you can run (from your terminal)

DISPLAY=:0.0 ; xhosts +

This is not a recommended long term fix as it completely disabled access control to your X server.
