is_scalar
(PHP 4 >= 4.0.5, PHP 5) is_scalar --
Finds whether a variable is a scalar
Descriptionbool is_scalar ( mixed var ) is_scalar() returns TRUE if the variable
given by the var parameter is a scalar,
otherwise it returns FALSE.
Scalar variables are those containing an integer,
float, string or boolean.
Types array, object and resource
are not scalar.
Замечание:
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.
