This technique is not recommended as it was used prior to the introduction of the ... token." I'd also note that using these functions (instead of "...$var") aren't so good for IDE's or Static Analysis, as the function signature does not clearly define the parameters exist (let alone type)... so these func_* functions might be candidates for deprecation, if anyone cares enough about them :-) Craig
