How Can I Produced Alpha Numeric In Php/SQL And Which Is A Better Approach?

Good day, I just would like to ask if how can I generate random Alpha Numeric characters using PHP code / MySQL Code. I want to insert these values as unique Id for the user. Instead of using the AI in MySQL.
.
It may sound stupid, but Which is better (Approach)?
Generating Unique Id, using Php/Sql programmatically?.
.
Range could be minimum of 20+ characters. E.g gHs51hJkw9106bwkdHwPV752

Answer

You can use this code below . Its associated with the current timestamp so that its unique as you are planning to use it for AI .

<?php
$len =22;

$rand = substr(str_shuffle(md5(time())),0,$len);

echo $rand;

?>
