Well, you could produce those randomly. Store all the PINs to a database
and before storing compare that it doesn't exist yet. Here is a piece of
code to produce PINs in _exactly_ that format you want. I've done it for
myself, but feel free to use it in any way you like:
<?
srand((double) microtime() * 1000000);
for ($i=0; $i < 3; $i++) { // $i < 3 tells you how many 'parts' there
should be
for ($n=0; $n < 5; $n++) { // $n < 5 tells you how many chars
there is in each part
$nType = rand(1,3);
if ($nType == 1) // A number between 0 - 9
$strChar = rand(0,9);
elseif ($nType == 2) { // A small letter between a - z
$strChar = chr(rand(65,90));
} elseif ($nType == 3) { // A capital letter between A -
Z
$strChar = chr(rand(97,122));
};
$strCode .= $strChar;
};
// If it ain't the last part, add the separator char
if ($i != 2)
$strCode .= "-";
};
?>

Subject: [PHP] Generating PINs
Hi All,
This is not really a PHP question, but seeing that the final application
will be in PHP, I figured this'll be the best place to start.
I have a client who wants to release a unique PIN for each product they
sell which works as a key to get more goodies on the website. How/where
can
I get a large number of PINs, much like a software key (e.g.
3HH5R-E59VB-7SX99 or similar)?
TIA
@lvin
