R3m/framework Function reference is.scalar

{is.scalar(Mixed $value)}

Finds whether the given variable is a scalar.
Scalar variables are those containing an int, float, string or bool. Types array, object and resource are not scalar.


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.
is_scalar() does not consider NULL to be scalar.

Returns true if value is scalar, false otherwise.
