Notatka: is_scalar() does not consider resource
type values to be scalar as resources are abstract datatypes
which are currently based on integers. This implementation detail should
not be relied upon, as it may change.
Parametry
var
The variable being evaluated.
Zwracane wartości
Returns TRUE if var is a scalar FALSE
otherwise.
