Description:
------------
Short of using an experimental extension that's not likely to be available on a default install, there appears to be no way to disable/enable echoing of stdin content when reading it.

A use case would be something like:

<?php
ob_implicit_flush(true);
echo "Please enter your password: ";
// code to disable echo here
$password = fgets(STDIN);
// code to re-enable echo here.

Python supports a fxn for the password input use-case:
http://docs.python.org/py3k/library/getpass.html?highlight=password

Equivalent of that would satisfy me.

You can do the equivalent on unixy systems this way, but, alas, doesn't work
on Windows, which many of our CLI script users have:


            $stty = `stty -g`;
            system("stty -echo");
            $input = trim(fgets(STDIN));
            system("stty $stty");

This seems beyond what we should be supporting in the core of PHP. I am sure 
there are ways of doing this on Windows. A quick search gets me the 
ScriptPW.Password component. It should be easy enough to trigger that via the 
COM extension.

eg.

$pwd = new Com('ScriptPW.Password');
