PHP实现的简单异常处理类示例

<?phpheader('content-type:text/html;charset=UTF-8');// 创建email异常处理类class emailException extends exception{}// 创建pwd异常处理类class pwdException extends exception{  public function __tostring(){    return $this->getMessage().'in file:'.$this->getFile().'on line:'.$this->getLine();  }}function reg($reginfo = null){  // 依据不同错误抛出不同异常  if (empty($reginfo) || !isset($reginfo)) {    throw new Exception('参数非法');  }  if (empty($reginfo['email'])) {    throw new emailException('邮件为空');  }  if ($reginfo['pwd'] != $reginfo['repwd']) {    throw new pwdException('两次密码不一致！');  }}// 接收不同异常，并针对性处理！try {  reg(array('email' => '1078789950@qq.com', 'pwd' => '123', 'repwd' => '1231' ));} catch (Exception $e) {  echo $e ->getMessage();} catch (emailException $ee) {  echo $ee ->getMessage();} catch (pwdException $ep) {  echo $ep;}
