Tama siya, para walang identical. Medyo challenging to if ever naka database kasi you need to check whether the generated serial number is already existing but varies on the format you like.
ex:

<?php
//gerate auto SSN based on current date and record number
//ex: 20210301/0002
 $datesn=date("Ymd");

 $rec_no=1; //record count, increment 1 if exxisting from the list
 //str_pad for padded string or with leading zeros with size of n
 //visit: https://www.php.net/manual/en/function.str-pad.php
    echo $datesn.'/'.str_pad($rec_no,4,0,STR_PAD_LEFT);
?>

uniqid() - The uniqid() function generates a unique ID based on the microtime (the current time in microseconds).

<?php
echo uniqid();
?>
