Is it appropriate to use time concatenation ( mktime() ) and auto increment to get a unique id?

Question

PHP

if I write elements with id obtained in this way to the database, will there be any pitfalls in the future?

<?php $id=0; ?>
<?foreach($data as $k=>$v):?>
<div id="<?=$id++ . mktime()?>">
Текст который нужно записать в базу, у него есть уникальный id
</div>
<a id="<?=$id . mktime()?>" href="<?=$v?>"><?=$k?></a>
<?endforeach?>

Answer 1

Normal, but it's really better to use autoincrement
