I expect this would be a problem for folks who are relying on the fact that they can parse configuration files and web inputs purely as strings, yet numeric fields containing string representations of numbers will actually behave as numbers if called upon to do so.
Speaking of which, when I'm in a hurry and large numbers (or negative numbers) are not dangerous in that particular context, I sometimes validate a numeric field like this: $x = $_REQUEST['x'] + 0; And then assume $x will be a number - perhaps an obnoxious number, maybe even a huge floating point number with an exponent, but a number. Is there a flaw in that reasoning that I'm not aware of?
