Why should the primary key be set to varchar type?
Maybe you have special needs! When inserting data, just like other fields, that’s it!

It means to use UUID, then you can use a program to generate UUID.

Then use uuid as the primary key

UUID as primary key insert

composer require ramsey/uuid

use RamseyUuidUuid;
$uuid1 = Uuid::uuid1();
echo $uuid1->toString()
