// Inputs:This script processes the username/password registered by the end user.
//
// Assumes:uses two functions--strlen() and substr()--and a "while loop." the strlen() function returns the length of anything that can be stored in a variable. The second, substr(), takes a part of anything that is stored in a variable. Example: $foo = Hello World;
$foofoo = substr($foo, 0, 7);
$foofoo == Hello Wor

$length = strlen($password); //Gets the length of the Password
$sub_password = substr($password, 0, 4);
//(Comment for the code above)This takes the original passwords and cuts it length.
//First, I plug-in the original variable. Then, the number at the beginning of the string.
//The second number controls how much of the password will be revealed.
//Remember that PHP starts counting at 0.
$length2 = strlen($sub_password);
//This gets the length of the password after is has been cut
echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">";
echo "<html><head><title>$title</title></head>";
echo "<br><br>";
echo "<div align=\"center\">Welcome $username your password is $sub_password";
while($length2 < $length)
{
print("*");
$length2++;
}
echo ", all but the first four are hidden for your security.</div>";
//(Comment for the code above)This is a simple While Loop--While the length of the original
//password is greater than the length of the cut password
//there will be "*" printed out. This is to reveal the
//first few characters of the password after registration, and the last few
//are replaced for security.

and the point of this? password should never be shown, not even few chars and this one even reveals lenght of the password...very bad. instead, if2!0you really want to show few chars of the password do it as in code but put like 8 stars after the stars so the real length would not be revealed.

i never seen this done anywhere. nowhere should the password be shown.
if the user doesnt know what the passowrd is he must be st00pid.. thats why they have 2 confirm textboxes so u can type them twice!

Its why sites ask you to confirm your password when typing it, so you know it.
I hate sites (like some forums) that email you your username/password in plain text.

Sites always ask you to confirm your password so that you can verify if you typed your password correctly not for you to know it.. It's your password so obviously, you know it when you type it.. duh..
