System command from PHP
 

HI,

To cut a long story short i want to be able to run this "cd /root/Desktop ; tar xvf /tmp/backup"command from my php interface.

Ive tried:
shell_exec("cd /root/Desktop ; tar xvf /tmp/backup")

To create the file in /opt/lampp/htdocs, then try and run the file.
vi runme
#start of file
cd /root/Desktop ; tar xvf /tmp/backup
'end of file
shell_exec("/opt/lampp/htdocs/runme");

ive tried to include the line in /etc/init.d/backup
but the sytnax i use doesnt seem to work.

Does anyone know of a way i can do this?

Thanks Rich

Whats the output/error ?? Try looking in http log files for errors.
