Auto generate a number

robin339 · March 6, 2007

Hello everyone,

I use an online ordering system. Is there a way to automatically generate a random 6+ digit unique number and also print the number on the confirmation page? I dont use mysql or any database.

Here is the link for the actual page. You can go ahead and submit something (just use "Test" on the name field)

Here are the codes:

If you want the number to be unique, you are going to have to store the previously used numbers somewhere. Since sql is not an option, would you be open to the idea of a text file "database"?

Of course.

Thanks :-)

robin339 · March 6, 2007

How would I go about doing that?

Thanks

robin339 · March 6, 2007

any thoughts?

Thanks

boo_lolly · March 6, 2007

it's pretty basic. check out this series of tutorials for working with flat files using php:

Not really. You could use some bastardization of the timestamp to get a unique id.

absolutely. in fact, this method is used more often than you'd think.

Thanks for the replies guys.

I am so lost. I have no experience with php :-(

everybody starts somewhere. your project is not a bad place to start. what are you having trouble understanding?

everybody starts somewhere. your project is not a bad place to start. what are you having trouble understanding?

I was reading through the link provided above. I did not understand which part comes into play as far as creating a unique ID. It describes "how to create, open, and close a file. How to read, write, append, truncate, and uploading files with PHP".

Honestly following are the only two things I need to find out how to achieve. I really dont need to keep track of the numbers later (like insert into a mysql or even a txt based database). The numbers and the info will get emailed to me. Dont need to save the information on the server.

Q. How do I create a field in my current page to generate an unique ID

Q. How do I "print" that Id in the confirmation page.

If it can't be done without some sort of database in place, then I will have more questions

Is there a way to manupulate and add commands to the exsisting process.php that I have above.

Thanks for answering my questions so patiently.

interpim · March 6, 2007

well... the reason you would need to store them is so that the script doesn't duplicate the "random" number again in the future.

How do I get my page to create a number?

How do I get my page to write the number on a file and read it for future refences?

here's how you generate a random number with 6+ characters:

<?php
        $totalChar = rand(6, 25);
        $salt = "1234567890";
        srand((double)microtime()*1000000);
        $keyGen=""; // set the inital variable

        for($i = 0;$ i< $totalChar; $i++)  // loop and create password
                $keyGen = $password . substr ($salt, rand() % strlen($salt), 1);
        }
?>

and the way you write this random digit to a flat file and then read from the flat file later is by using the tutorial i provided for you in previous posts.

boo_lolly · March 6, 2007

sorry, the key generator is wrong... this is what you want:

<?php
        $totalChar = rand(6, 25);
        $salt = "1234567890";
        srand((double)microtime()*1000000);
        $keyGen="";

        for($i = 0;$ i< $totalChar; $i++){
                $keyGen .= substr ($salt, rand() % strlen($salt), 1);
        }
?>

robin339 · March 6, 2007

ok thanks.

this is what i got so far..

<?php
include("global.inc.php");

// generate a number
$totalChar = rand(6, 25);
        $salt = "1234567890";
        srand((double)microtime()*1000000);
        $keyGen="606778"; // set the inital variable

        for($i = 0; i< $totalChar; $i++)  // loop and create password
                $keyGen = $password . substr ($salt, rand() % strlen($salt), 1);
//
$ourFileName = "ordernumber.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);

// open for writing
$myFile = "ordernumber.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $keygen);
fclose($fh);

// close file

I created a file called ordernumber.txt and CHMOD 777

The page doesnt load

there's a syntax error in the for conditions.

'i' needs to be '$i'

ok

now i have this

<?php
include("global.inc.php");


// generate a number
$totalChar = rand(6, 25);
        $salt = "1234567890";
        srand((double)microtime()*1000000);
        $keyGen="606778"; // set the inital variable

        for($i = 0; $i< $totalChar; $i++)  // loop and create password
                $keyGen = $password . substr ($salt, rand() % strlen($salt), 1);


$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Test Text\n";
fwrite($fh, $salt);
fclose($fh);

It does write, but the only thing it writes is 1234567890, if i put $keygen in fwrite

($fh, $keygen);

it doesnt write anything.

Thanks so much for the help man :-)

no problem buddy. try this:

<?php
        $totalChar = rand(6, 15); // number of chars in the password
        $salt = "1234567890";  // salt to select chars from
        srand((double)microtime() * 1000000); // start the random generator
        $serialNum = NULL; // set the inital variable

        for($i = 0; $i < $totalChar; $i++){
                $serialNum .= substr($salt, rand() % strlen($salt), 1);
        }

        $myFile = "testFile.txt";
        $fh = fopen($myFile, 'w') or die("can't open file");
        $stringData = "Test Text\n";
        fwrite($fh, $serialNum);
        fclose($fh);
?>

Wouldn't it be easier to take the CRC32 checksum of some data added together from whatever is already unique, say the username for instance.

what makes you think there will be a username? i'm not sure, but i'd say that's part of the reason why he wants to generate a serial number for the customer.

@robin339: why does it have to be only numbers? why can't it contain letters? if this is feasible then you could just use session_id().

<?php
        session_id();
        session_start();

        /*boom*/
?>

I have created a blank document with

<?php
        $totalChar = rand(6, 25);
        $salt = "1234567890";
        srand((double)microtime()*1000000);
        $keyGen="";

        for($i = 0;$ $i< $totalChar; $i++){
                $keyGen .= substr ($salt, rand() % strlen($salt), 1);
        }
?>

but i have an error:

Notice: Undefined variable: 0 in /var/www/vhosts/cowperrecruitment.co.uk/httpdocs/keygen.php on line 7

but it keeps increasing, so i'm currently up to 95621....

I just want to echo the $var for 305 different numbers...

I also need to generate 305 random unique codes... can I add some code to make it repeat 305 times?
