如何在没有密码的情况下从 php 脚本运行 sudo su？

Question

I am making a PHP script in which I have to send mail with attachment. I am using mutt and the command is...

echo 'This is the body' | mutt -s 'Testing mutt' 1nonlyabhishek002@gmail.com -a /home/jyoti/ab.txt 

...but the problem I am facing is that it works only with sudo su so I want to use sudo su in my PHP script without password. Please suggest me the way I can run sudo su in my PHP script.

I will be happy if there is way to run using password in script, that would be fine too. All I want is to execute the above command with sudo su with password or without password. Security doesn't matter.

Allow the web server user to run your script with no password, add to your sudoers file, in this example apache is the web server user:

apache ALL=NOPASSWD: /path/to/your/php/file.php 

You can use visudo to edit the sudoers file.
