Rand() Function (6 Digits)

44ozCoors

Hey, Im trying to generate a random number sequence..
What I need it to do, is start at 201 And go up.
Basically it will look like this (this is what I did so far)
So, as user's register it goes up by one: IE
MAI201, MAI202, and so on...

Your New Pilot ID is: MAI <? echo(substr(sha1(uniqid(rand(), true)),1,6)); ?> 
Your New Password is: <? echo(substr(sha1(uniqid(rand(), true)),1,6)); ?> </html>

One other thing I need is, later on Ill be implimenting a mail()
function to send the username and password to the user
and Im curious how to delcare the username/password
as variables (so that when Im typing the welcome letter)
I can get the username/password in the email

Thanks guys

You'll need two files to do this (I think):

------count.txt------
201
------end count.txt------

------pre-done.txt------
------end pre-done.txt------

------register.php------
<html>
<head>
<?
$file = File("count.txt");
$count = $file[0];
$PilotID = $count;
$count++;
file_put_contents(str_val($count), "count.txt");

$file = File("pre-done.txt");
$is_ready = 0;
$random;
while($is_ready)
$random = rand();
for($i = 0; $i++; $i < count($file))
if($random == $file[$i])
{
$is_ready = 0;
break;
} else $is_ready = 1;
};
$Password = substr(str_val($random), 1, 6);
$text = "";
for($i = 0; $i < count($file); $i++) $text .= " " . $file[$i];
$text .= " " . $Password;
file_put_contents($text, "pre-done.txt");
?>
</head>
<body>
Your New Pilot ID is: MAI<?= $PilotID ?> 
Your New Password is: <?= $Password ?>
(other stuff)
</body>
</html>
------end register.php------
