What are the potential security risks of using sudo in a PHP script?

When using sudo in a PHP script, there is a risk of allowing unauthorized access to system commands and potentially compromising the server's security. To mitigate this risk, it is recommended to use a more secure approach such as implementing proper user permissions or using a secure communication method like SSH. 

// Example of a more secure approach using PHP's built-in functions to execute commands with proper user permissions
$command = 'ls -la';
$output = shell_exec('sudo -u www-data ' . $command);
echo $output;
