In your standard function library yeah? ;)

Just pointed it out, as it's normally no problem in PHP to juggle types as
one goes, but the difference between scalar & non-scalar is often
significant for functions, so a simple test is_scalar() offcourse beats
(!is_array()&&!is_object()&&!is_resource()) or (is_string()||is_float()).
