When users register in my webpage, their information is sent to me correctly, but their password shows up like this: *3543A0AD7EA1BA D
How can I make the passwords to come out as the users wrote them?

And, when they finish registering this code comes up:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/16/7266916/html/register.php:1) in /home/content/16/7266916/html/register.php...
