(^198) CHAPTER 13 ■ SPL EXCEPTIONS
Just the Facts
This chapter covered the following SPL exceptions:- LogicException handles exceptions that are detectable at compile time—when the
application is programmed incorrectly. - RuntimeException handles exceptions that can be detected only at runtime.
- BadFunctionCallException handles exceptions due to illegal function calls.
- BadMethodCallException handles exceptions due to illegal method calls.
- DomainException handles domain exceptions. A domain is the set of all input values that
are valid for a function. - RangeException handles range exceptions. A range is the set of all output values that are
valid for a function. - InvalidArgumentException handles cases where a function or method receives an
invalid argument. - LengthException handles exceptions due to length, such as too many elements in an array.
- OverflowException handles exceptions due to overflow conditions—arithmetical overflow
or overflow in the storage location. - UnderflowException handles exceptions due to a value being too small to maintain
precision, resulting in loss of accuracy. In PHP, this can occur when using floats.
