The UnexpectedValueException class

(PHP 5 >= 5.1.0, PHP 7, PHP 8)


Exception thrown if a value does not match with a set of values. Typically this happens when a function calls another function and expects the return value to be of a certain type or value not including arithmetic or buffer related errors.
