Re: Raise E_NOTICE for null castings

Hi, I would like to propose an RFC to raise an E_NOTICE when a variable "initialized" to null is casted to other types: $foo = null; var_dump($foo['bar']); var_dump($foo . 'bar'); var_dump($foo + 2); var_dump($foo & 2); // At the time being, this code produces no errors The eventual vote may be split one for each case. What do you think?

pleae don't break code like this which is a useful case for access directly a array field returned from a function and so makes this to a one-liner without check the result public function GetMaxSort(): int { return (int)mysqli_fetch_row($this->cl_api->db->query("select SQL_NO_CACHE max(hsort) from {$this->cl_api->sql_prefix}main", 1))[0]; }
