我的例子:
class CustomException extends \Exception { } class FirstClass { function method() { try { $get = external(); if (!isset($get['ok'])) { throw new CustomException; } return $get; } catch (Exception $ex) { echo 'ERROR1'; die(); } } } class SecondClass { function get() { try { $firstClass = new FirstClass(); $get = $firstClass->method(); } catch (CustomException $e) { echo 'ERROR2'; die(); } } } $secondClass = new SecondClass(); $secondClass->get();
这让我回复“ERROR1”,但我想从SecondClass收到“ERROR2”.
在FirstClass块中,try catch应该处理来自external()方法的错误.
我该怎么做?
解决方法
您应该抛出另一个异常并注册一个全局异常处理程序,而不是打印错误消息并终止整个PHP进程,该异常处理程序对未处理的异常进行异常处理.
class CustomException extends \Exception { } class FirstClass { function method() { try { $get = external(); if (!isset($get['ok'])) { throw new CustomException; } return $get; } catch (Exception $ex) { // maybe do some cleanups.. throw $ex; } } } class SecondClass { function get() { try { $firstClass = new FirstClass(); $get = $firstClass->method(); } catch (CustomException $e) { // some other cleanups throw $e; } } } $secondClass = new SecondClass(); $secondClass->get();
您可以使用set_exception_handler注册一个全局异常处理程序
set_exception_handler(function ($exception) { echo "Uncaught exception: ",$exception->getMessage(),"\n"; });
