We > already can get the error from json_last_error() if we want to) The main problem with not throwing a warning is that it makes debugging the error quite hard. json_last_error() only gives you an error code. So you have to use some script like the one used as an example in php.net/json_last_error to figure out what the particular error code actually means. This is obviously a lot more inconvenient than simply seeing "Oh, this failed because I passed an Inf". Nikita
