empty

empty checks if a variable is an empty string, an empty sequence, an empty mapping, exactly false, or exactly null.

For objects that implement the Countable interface, empty will check the return value of the count() method.

For objects that implement the __toString() magic method (and not Countable), it will check if an empty string is returned.
