How can I generate a number that never be the same again in php

How can I generate a number that never be the same again in php
it should be unique in life time
i want to use it as unique identifier

mulitpling uniqid () and rand () can be genreate 16 digit unique number each time


<?php 
 
echo uniqid()*rand();
?>

I tried an crazy way to create a random string with numbers and characters.


echo uniqid(rand(rand(),rand()));

or another crazy way but it only refresh last some character.


echo uniqid(rand(uniqid(rand())));

use random_int alternative of the rand () function , but we need to provide the min and max range to the random_int .


uniqid( random_int(1,1000000000000000));

rand() generate random number in php
we can make a unique id from random generated number.


echo uniqid(rand());

uniqid() can also create the unique code also .
