How Can I Execute Sudo-Protected Shell Scripts from PHP Without Password Prompts?

Executing SUDO-Protected Shell Scripts in PHP

Integrating shell scripts into PHP applications can enhance functionality, but encountering authentication challenges with scripts requiring SUDO privileges can be a hindrance. To seamlessly execute these scripts without password prompts, consider the following solution:

Instead of passing the password through the SUDO call, modify the sudoers file (/etc/sudoers) using the 'visudo' command. Append a rule that authorizes the web server user (usually 'www-data') to execute the specific script without a password:

www-data ALL=NOPASSWD: /path/to/script

This allows the user to execute the script via PHP's 'shell_exec' without the need for manual password input, enabling efficient script execution.
