It's not a unique value:

That's why I'm using uuidv4.

Generated with random_bytes.

Thanks. I am going to try random_bytes(8). The combo of my sort field and my campaign field should be pretty unique.

This line is failing:

$data['date_time']=random_bytes(8);  //this is to create a unique number

When I step through this line with the debugger, the code just crashes. (ie it gets stuck at this line). I am getting this apache error:

 PHP Fatal error:  Call to undefined function random_bytes() in C:\\xampp\\htdocs\\sub_crud\\application\\controllers\\Subit_backend.php on line 364

You need PHP 7+.

You can also get a unique number using the below.

PHP Code:

$data = openssl_random_pseudo_bytes(16); 


It is part of PHP.
