在「PHP: rfc:json_throw_on_error」這邊提到 PHP 7.3 會解決 json_decode() 發生錯誤時的處理方式:

PHP has two functions for dealing with JSON, json_decode() and json_encode(). Unfortunately, both have suboptimal error handling. json_decode() returns null upon erroring, but null is also a possible valid result (if decoding the JSON “null”).

在這之前唯一的判斷方式是另外再呼叫 json_last_error() 或是 json_last_error_msg(),但這樣寫很辛苦,所以要引入 JsonException 了,總算...
