generate password

Anon

hai

Do anyone know how to create password randomly by the code.Example:-
Code =VVVVV11111111 to VVVVV11111122

Each code i need a diffrent password.
Currently i'am using database to create it by the code and not saved in database.Actually this way is not a good solution because it's possible to break.
Example of database password where it's almost same:-
VVVVV11111111 535c17e46c2b1fac
VVVVV11111112 535c10b96c2b1881
VVVVV11111113 535ced4e6c2a6516
VVVVV11111114 535cee636c2a662b
VVVVV11111115 535ceb386c2a6300

if anyone knows please help me.

Thank IN advance.

One method is to say:

srand(); // somewhere...
...
$password = md5 (uniqid (rand()));

This generates a 32-character string, which is probably too long for most uses. Just take the leftmost N characters, and you're done.

Not sure if this will help you or not...I threw a simple script that will generate random passwords to a specified length, that you specify.

<?

$form = "
<FORM METHOD=\"POST\" ACTION=\"$PHP_SELF\">
Password Length: <INPUT TYPE=\"text\" name=\"len\"><BR>
<INPUT TYPE=\"submit\" name=\"submit\" value=\"submit\">
";
function randpw($length) {
$possible = '0123456789~!@#$%^&()_+' .
'abcdefghijklmnopqrstuvwxyz' .
'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
mt_srand((double)microtime() 1000000);
$str = "";
while(strlen($str) < $length) {
$str .= substr($possible, mt_rand(0, strlen($possible) - 1), 1);
}
return $str;
}

if($len) {
    $this = randpw($len);
    echo "<FONT FACE=\"Verdana\" Size=\"2\">".$this."</FONT>";
    echo "<BR><FONT FACE=\"Verdana\" Size=\"1\"><A HREF=\"javascript:history.go(-1)\">Back</A></FONT>";
} else {
    echo $form;
}

hi Jeremy

Thanks for your reply.I already go threw
it but i can't understand.Ok i explain what
is my situation is.Actually i want to generate password for the requester.Let's say
the requester want to 20 passwords.So i need
to create 20 passwords.Here i already create
20 user ID, from VVVVV11111111 to VVVVV111111131.
Now i need 20 passwords for that 20 user ID.
This passwords should not save in database.Then,the user will login using the user ID and password
that given to them.when the user login we have check the password by using
the method we use to create it.Is it your
coding for this situation.If yes please explain to me.Thank You

If you want fewer than 32 characters, say:

$show_pass = substr( $passwd, 0, 12 );

This gives you a 12-char string.
