There's no (and shouldn't be any) significance in the order of the arguments.

additionaly, IMHO, as php has to deal with html forms a lot and html has no <input type=numeric> there are a lot of places where a string that qualifies as is_numeric is silently treated as a numeric argument

Right, that's why PHP automatically compares two string-like strings as if they were numbers. Zeev
