Question

I installed cutycapt as root user
I tried it from command prompt

xvfb-run --server-args="-screen 0, 1024x768x24" /root/cutycapt/CutyCapt/CutyCapt --url=http://www.poochh.com --out=/tmp/example.png

But when I am executing it from php exec()
I am getting this error on var_dump($output); of exec()

array(1) { [0]=> string(80) "/usr/bin/xvfb-run: line 166: /root/cutycapt/CutyCapt/CutyCapt: Permission denied" }

Answer 1

Check the user php runs as! You may need to make sure it has rights to run cutycapt

Try running

echo exec('whoami'); 

to check who php is running as
