Changes in pdo_sqlite and var_dump in PHP 8.1

php.internals

Hi Internals, While trying to run Doctrine DBAL test suite on PHP 8.1, I noticed a few differences in PHP 8.1 behavior compared to the earlier versions: 1. pdo_sqlite returns integer and decimal columns as PHP integers and floats respectively instead of representing them as numeric strings. See https://3v4l.org/YDUfj. 2. var_dump() outputs the properties declared in a parent class before the class's own properties. Previously it was the other way around. See https://3v4l.org/EKEHN. I can't find anything related in the PHP 8.1 RFC list <https://wiki.php.net/rfc#php_81> or by briefly looking at the code changes. Are these changes expected, and if so, what's their source? Thanks!
