 New Comment:

Created a new, more appropriate bug here

https://bugs.php.net/bug.php?id=76386

and commented a lot there.

The solution proposed here does not work as it has been written for a fixed precision of 6, whilst
MySQL supports any precision between 0-6.

I also created a proper fix and sent a pull request that did not make any tests fail.
See here:

https://github.com/php/php-src/pull/3257

I am unsure when it will be merged and into which release though (even though it is 100% backwards
compatible).

Thanks for the follow up, it was very useful.

It is apparent that, regardless I did not get the error with mysqli, it is not a bug with PDO per se
but instead the prepared statement handler in mysqlnd.
(That shall mean it would have had happened with mysqli as well had I used prepared statements.)

I try and open a bug with them then.

(No wonder I did not find anything in the PDO sources. :P)

I've found possible solution: https://github.com/andrewmackrodt/php-pdo-fractional-bug/pull/1/commits/50552212b77b1b1021918ba98f45b1866b0fb057

This is indeed a problem with PDO; when using mysqli, the issue is not apparent.

Can anybody elaborate if this is really a problem with PDO itself, or, rather, is the cause the
underlying mysqlnd (that is still 5.0.12-dev from 2015)?

Any updates on this? I can confirm that it still exists as of 7.1.5
