The if statement which checks the ingredient amount, if($amount != null && !is_float($amount) && !is_int($amount)), why use and instead of or? As she said later herself or....or?

501 PointsI don't know what's the context behind this code, but if any of those conditions returns false, the entire if statement will be skipped, even if one of them is true it won't matter

501 PointsThere she is doing that to check if there is a value inside $amount that is: checking whether or not you entered a value for $amount, and then checking if that value is not float value, and then checking if that value is not an int value, if any of those conditions return true, then the script shall end, so if for example you enter a string value such as: "2" for amount within quotes the script will end because $amount is not empty, and $amount is not a float, and $amount is not an int value just as she says in the video and in the code, if on the other hand there isn't a value entered into that value, let's say you don't pass in that argument, then the program shall continue, as she says $amount and $measure are optional, so they are set to NULL by default
