I am running a cli-script, that requires a exec('sudo ...'); call. I know it is not safe on the web, but how can it be done in cli? The script is executed by a user known as "btcdbit", who is in the sudoers file.

In my experience setting the NOPASSWD option doesn't always work and even if it does it seems unsafe. Seems to me that a better approach - if you're able to use it - would involve using phpseclib to do sudo through SSH. eg.
<?php include('Net/SSH2.php'); $sftp = new Net_SSH2('www.domain.tld'); $sftp->login('username', 'password'); echo $sftp->read('username@username:~$'); $sftp->write("sudo ls -la "); $output = $sftp->read('#Password:|username@username:~\$#', NET_SSH2_READ_REGEX); echo $output; if (preg_match('#Password:#', $lines)) { $ssh->write("password "); echo $sftp->read('username@username:~$'); } ?>
