How I can generate the unique ID in laravel?

I’m working with my graduation project in Laravel, and want to generate small unique ID "9 char max" ... I don't need UUID because this will generate 36 char which is too long.

You can use the PHP function like this:

function unique_code($limit)
{
  return substr(base_convert(sha1(uniqid(mt_rand())), 16, 36), 0, $limit);
}

echo unique_code(9);

The output looks like this:

s5s108dfc

Here are the specifications:

• base_convert – Convert a number between arbitrary bases.
• sha1 – Calculate the sha1 hash of a string.
• uniqid – Generate a unique ID.
• mt_rand – Generate a random value via the Mersenne Twister Random Number Generator.

Or in Laravel you can use laravel Str library: just use this:

use Illuminate\Support\Str;
$uniqid = Str::random(9);

:::NOTE:::

While this function may produce unique codes for a certain period, it is not guaranteed to always generate unique codes. You should need to cross-check every time with existing codes in your system.
