unique-codes's Issues
Deprecated function: PHP 8.1
- Package version: 2.0.0
- PHP version: 8.1
Description:
Deprecated function: Implicit conversion from float 222886.09677419355 to int loses precision in NextApps\UniqueCodes\UniqueCodes->encodeNumber() (line 227 of…/vendor/nextapps/unique-codes/src/UniqueCodes.php).
Code in UniqueCodes:227 generates a float value. This will be cast to interger for using as array key.
Steps To Reproduce:
Just generate a code into a PHP 8.1 environment.
Hotfix
Cast $digit into a integer on line UniqueCodes:229
protected function encodeNumber(int $number)
{
$string = '';
$characters = $this->characters;
for ($i = 0; $i < $this->length; $i++) {
$digit = $number % strlen($characters);
$string = $characters[(int)$digit].$string;
$number = $number / strlen($characters);
}
return $string;
}
Question
I've a question, two primes number that you need to obfuscate sequential number, must be coprimes?
In this link:
https://web.archive.org/web/20170730030023/http://blog.mischel.com/2017/06/20/how-to-generate-random-looking-keys/
const long m = 101; // Number of keys + 1
const long x = 387420489; // must be coprime to m
Generated codes look like they are being padded to reach requested string length
- Package version: 2.0.0
- PHP version: 8.0
Description:
Generated codes prepend the first character of the character map to fill the generated code to the requested length - or so it looks, I'm no mathematician, and thus cannot offer any help in solving it.
Steps To Reproduce:
(new \NextApps\UniqueCodes\UniqueCodes())->setObfuscatingPrime(30402457)->setMaxPrime(25964951)->setCharacters('rn5ze6xatdkv9picsh10fm8g')->setLength(16)->generate(1, 100, true);

Parameters in config file?
- Package version: n/a
- PHP version: n/a
Description:
Currently, I believe a developer must specify both primes, plus the list of characters, plus any other parameters they wish to supply, each time they call UniqueCodes().
I use Laravel and I'd love to be able to put all those config items in a config file, so that I don't need to supply them in the main body of my code.
Does that sound like a good idea? Would the project maintainers be keen to see a PR, if I put one together?

A question
Description:
I've read your post about the source(https://gdebrauwer.dev/blog/generating-unique-voucher-codes/). But i get different result, I don't know why?
encodeNumber(1) == 213456
encodeNumber(665281) == 24ECAD
encodeNumber(1) != encodeNumber(665281)
Can you give me the answer, thank you!
