Running this code on PHP (7.3.16 / 7.4.2 / 7.4.4) still results in same behaviour. 
I do not know nor test it on sqlite.

Oops, this is exactly the same as with pdo_mysql.

I can confirm the broken behavior.  Interestingly, pdo_sqlite3
also repeats the driver specific error code and message, but has
the SQLSTATE error reset to zero.

Guys it's not a SQL BUG, it's the error code that not being reset.
Please READ the description and look at the results.
Please look at array(3) of both the Expected result and Actual result

"Duplicate entry 'php-rulez' for key 'PRIMARY'"

Look up this Link: https://dev.mysql.com/doc/refman/5.7/en/constraint-primary-key.html

If you are beginner in using SQL, take a look at this side: https://www.w3schools.com/sql/sql_primarykey.asp
