I need a code generator

I need a 16 digits php/mysql code generator, please

find on google search engine. You'll definitely find one.

On it sir! When should I have that to you by? I know it's the weekend but I'm willing to work my butt off to fulfill this eloquent request. Do you need anything else done while I am at it? Perhaps some more code I could write for you, that way you don't have to learn anything!

What do you mean code generator? Just a random 16 digit string?

For digits:

function CreateRandomCode($len) {
$chars = "1234567890";
srand((double)microtime()*1000000);
$string = '' ;
$len++;

for ($i=0;$i<=$len; $i++) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$string .= $tmp;
}
return $string;
}

or

function CreateRandomCode($len) {
$chars = "abcdefghijklmnopqrstuvwxyz1234567890";
srand((double)microtime()*1000000);
$string = '' ;
$len++;

for ($i=0;$i<=$len; $i++) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$string .= $tmp;
}
return $string;
}

for letters and numbers


Use the function like this:
$random = CreateRandomCode(16);
