当异常被抛出时,其后的代码不会继续执行,PHP 会尝试查找匹配的 "catch" 代码块。 如果异常没有被捕获,而且又没用使用 set_exception_handler() 作相应的处理的话,那么将发生一个严重的错误(致命错误),并且输出 "Uncaught Exception" (未捕获异常)的错误消息。

Python 内置异常类(Exception),Python中即使语句或表达式在语法上是正确的,但在尝试执行时,它仍可能会引发错误。在执行时检测到的错误被称为*异常*(Exception),异常(Exception)不一定会导致严重后果。为方便处理异常(Exception),Python中会有提供的内置异常类(class)。
