Yes it is ... and it also works on Windows ...
This is PEAR's Console_CommandLine_Action_Password::_promptPassword() method.
private function _promptPassword()
{
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
fwrite(STDOUT,
$this->parser->message_provider->get('PASSWORD_PROMPT_ECHO'));
@flock(STDIN, LOCK_EX);
$passwd = fgets(STDIN);
@flock(STDIN, LOCK_UN);
} else {
fwrite(STDOUT,
$this->parser->message_provider->get('PASSWORD_PROMPT'));
// disable echoing
system('stty -echo');
@flock(STDIN, LOCK_EX);
$passwd = fgets(STDIN);
@flock(STDIN, LOCK_UN);
system('stty echo');
}
return trim($passwd);
}
Essentially fgets(STDIN) is the key.
On windows you have to press enter. Even if you try using fgetc().
