DateTime was not needing any special care, but now it would because the behavior changed between php 7.3 and 7.4, IMHO, it's a BC break. Not https://3v4l.org/rdhKg: another change in the bevahior of \Datetime casting. ------------------------------------------------------------------------ [2019-08-07 16:30:17] cmb@php.net Well, then ... :) ------------------------------------------------------------------------ [2019-08-07 16:25:35] nikic@php.net We could easily restore the previous behavior wrt array casts here -- we're already keeping compatibility with json_encode() for example. What's the use case? ------------------------------------------------------------------------ [2019-08-07 16:21:11] cmb@php.net > Casting to an array is undefined, […] Not wrt. objects[1]: | An array converts to an object with properties named by keys and | corresponding values. Anyhow, this is a deliberate change[2]; DateTime objects are not supposed to have public properties.
