The What
Description
Finds whether the given variable is a scalar.
Scalar variables are those containing an integer, float, string or boolean. Types array, object and resource are not scalar.
Note:
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.
Note:
is_scalar() does not consider NULL to be scalar.
If you listen carefully, you can hear the 1s and 0s flowing in your computer.
