Exceptions are used to handle (unforseen) Error Conditions within your Application and offer a comfortable way of Error Handling. Languages like Java implement Exceptions in a rather strict way (checked Exceptions, Propagation), whereas in PHP5, Exceptions are used as an addon which you can use, but don't have to. To use this mechanism, try/catch-block support is provided. This means, you can execute code in a sandboxed environment and react on possible failures of the called code.
