When you retrieve values from $_GET, they are URL decoded. If you want to pass it back, you need to encode it again, so that newlines, spaces and other weird characters gets encoded. Use urlencode($text) for this.

$text = $_GET['text'];
header("Location: https://web.whatsapp.com/send?phone=00000000&text=".urlencode($text));
