Structured programming says you should only ever have one return statement per function. This is to limit the complexity. Many people such as Martin Fowler agrue that it is simpler to write functions with multiple return statements. He presents this argument in the classic refactoring book he wrote. This works well if you follow his other advice and write small functions. I agree with this point of view and only strict structured programming purists adhere to single return statements per function.
