Re: [PHP-DEV] [Discuss] Add PDO disconnect() and isConnected()

[Kamil Tekiela]

I find this proposal to be a backwards step in the age when we are
moving away from resources and their explicit closure. We have
disabled this in PHP 8.0 for curl_close(), imagedestroy(),
openssl_pkey_free(), shmop_close() and xml_parser_free(). Sure,
mysqli_close() still works, but the whole extension is mostly a
historical artefact and a bunch of bad design choices due to what that
extension is (quick replacement of mysql_* API). PDO was designed much
better and it deliberately avoided the foot gun that is explicit
connection closure. I really wish we would not introduce bad design
choices into the language, and because of this, I wish this proposal
were unsuccessful.
