php7中系统自带异常类和自己创建异常类

1,系统自带异常类 try catch <?php try{ throw new Exception('96net.com.cn',10); }catch(Exception $e){ echo $e->getMessage(); echo $e->getCode(); }

2,自己创建异常类

<?php class MyException extends Exception{ function demo(){ echo "dc3688.com"; } } try{ throw new MyException('96net.com.cn',10); }catch(Exception $e){ echo $e->getMessage(); echo $e->getCode(); echo $e->demo(); }
