Indeed. As an example, the following command ought to prompt for a
password and save it into a file called "foo" without echoing it to the
command line:

stty -echo; echo -n 'Password:'; head -n1 >foo; echo ''

with a bit of imagination, it should be pretty easy to see how you can
work this into a PHP program:

<?php
echo 'Password: ';
$pwd = preg_replace('/\r?\n$/', '', `stty -echo; head -n1`);
echo "\n";
echo "Your password was: {$pwd}.\n";
?>
