This works, so exec function is not disabled.
exec('ls');
This doesn't work even thought script.php has 777 chmod.
exec('php script.php');
This doesn't work either.
exec('php -v');
I tried to chmod and chown /var/www/ folder, but it doesn't help. I suppose this is due to the www-data user permissions, looks like it doesn't have access to several bin files.
How can I solve this?
try
which php
and then get the path and put it in exec() like
exec("/opt/local/bin/php -v");
