In particular, the following inputs are rejected with a TypeError when fed to a function that accepts an int: "3 mices", null, [ ]. Most notably, no type conversion is performed when the input type is null or array, or when the target type is array or object. For reference, the original conversion rules are here: https://wiki.php.net/rfc/union_types_v2#coercive_typing_mode <https://wiki.php.net/rfc/union_types_v2#coercive_typing_mode> (I don’t know if there has been adjustments since then.) —Claude
