Execute python in a php script using shell_exec()

Question

I\'m experiencing a weird problem in trying to execute python in a php server (LAMP). (safe_mode off)

if I type:

$output = shell_exec(\"ls -lah\");
e         


        

Answer 1

Most likely the web server doesn't have appropriate rights to execute shell commands. To fix this, run the 'sudo visudo' command and add the following line to the sudoers file:

www-data ALL=NOPASSWD: ALL

Also, make sure that the /var/www directory belongs to the www-data user and group (use sudo chown -R www-data:www-data /var/www to set the correct owner). The details are here http://www.raspberry-pi-geek.com/Archive/2014/07/PHP-on-Raspberry-Pi
