Random Code Generator

[ansipants]

Ok, so I'm attempting to work on a script that will generate random codes and I also want to be able to change the multiplier with a form. Here is what I have so far:

 

<code>

 

 

<?php

$chars = "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // Alpha numberic character

$chars .= "123456789";

$chars .= "123456789";

$chars .= "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

$chars .= "123456789";

$chars .= "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

$chars .= "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

$chars .= "123456789";

$chars .= "123456789";

$chars = str_shuffle($chars);

$chars = substr($chars, 0, 15);

 

/** This is the part I'm not sure how to do because

it generates the same codes 5 times in a row and I want

it to generate different codes on each line or maybe do a form that

I can change the multiplier number to generate more

*/

 

$input = $chars;

$multiplier = 5;

$separator = "<br>\n";

print implode($separator, array_fill(0, $multiplier, $input));

print "<br>\n";

 

?>

</code>

 

Sorry I'm a n00b and trying to learn more =)

$input is the random string. You generated it a few lines before. All you do with it is repeat it $multiplier times.

If you want a different random string each time then you have to repeat the part that generates it.

<?php

$letters    = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // Alpha characters
$numbers    = "123456789"; //Numeric characters
$characters = str_repeat($letters, 4) . str_repeat($numbers, 9);

$multiplier = 5;
$length = 15;
$separator = "<br>\n";

$codes = array();
for($i=0; $i<$multiplier; $i++)
{
   $rand_chars = str_shuffle($characters);
   $codes[] = substr($rand_chars, 0, $length);
}

print implode($separator, $codes);
print "<br>\n";

?>
