Answer 3

Found a solution, that works in both cmd and GitBash. However, this is the ugliest implementation of clearing console-screen I can think of. Pity, that there isn't any working alternative.

The "magic" is to... poke console with fifty new-lines, like that:

public function clearStdin()
{
    for ($i = 0; $i < 50; $i++) echo "\r\n";
}

This is a modified (fixed?) version of this non-working (for me) post from 2006.
