command line evidence prompt php

i'm minute management line apparatus assistance web app. needs evidence bond service. i'd book arrangement evidence prompt i don't have pass management line argument.

that's easy enough, nonetheless i'd relate evidence shade it's typed. i php?

bonus points doing pristine php (no system('stty')) replacing characters *.

edit:

the book run unix component (linux mac). book combined php, many approaching stay that.

also, record, stty proceed doing is:

echo "password: ";
system('stty -echo');
$password = trim(fgets(stdin));
system('stty echo');
// supplement new line given users cr didn't echo
echo "\n";

i'd move have system() calls there.
