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();
这回复给我“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?

而不是打印错误消息并死于整个php进程,你应该抛出另一个异常并注册一个全局异常处理程序,它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();
$secondClass->get();
您可以使用set_exception_handler
set_exception_handler(function ($exception) {
echo "Uncaught exception: " , $exception->getMessage(), "\n";
});
