    Is there a particular reason *not* to pass an extra parameter to

Yeah, internal functions don't like extra parameters, e.g.:

  is_numeric('123', 4);

Warning: is_numeric() expects exactly 1 parameter, 2 given in php shell code on line 1


Ah, yes, I always forget that internal functions behave rather differently from user-defined ones when it comes to parameter passing.
