“如何在php中创建随机变量clickid?”

I have a large amount of traffic and click on an ad at the same time. I need to create a random value to make the value of those clicks and not be duplicated. I tried many random ways but there was still a duplicate problem.

PHP 5

$random=bin2hex(mt_rand());
$clickid=md5($random);

I want clickid is not duplicate when large amount of traffic and click on an ad at the same time.

    How about just concatenate multiple mt_rand()?

    $id = mt_rand().mt_rand().mt_rand().mt_rand().mt_rand().mt_rand().mt_rand();
    

    If you need a minimum length unique id, you need to save the previous id in some database and get the increased counter in the transaction.
