有沒有辦法在類的方法中使用自定義異常處理程序，而不是默認異常處理程序__destruct？例如：function myExceptionHandler($e){ echo "custom exception handler"; if(is_object($e) && method_exists($e,'getMessage')) echo $e->getMessage();}set_exception_handler('myExceptionHandler');class MyClass { public function __construct() { // myExceptionHandler handles this exception //throw new Exception("Exception from " . __METHOD__); } public function doStuff() { // myExceptionHandler handles this exception //throw new Exception("Exception from " . __METHOD__); } public function __destruct() { // default exception handler throw new Exception("Exception from " . __METHOD__); }}$myclass = new MyClass();$myclass->doStuff();即使在方法set_exception_handler內調用__destruct，仍使用默認處理程序： public function __destruct() { $callable = function($e) { echo "custom exception handler".PHP_EOL; if(is_object($e) && method_exists($e,'getMessage')) echo $e->getMessage(); }; set_exception_handler($callable); throw new Exception("Exception from " . __METHOD__); // default exception handler }

也許是這樣的？
<?php
class MyException extends Exception {
public function __construct() {
parent::__construct('my exception');
}
}
class MyClass {
public function __construct()
{
// myExceptionHandler handles this exception
//throw new Exception("Exception from " . __METHOD__);
}
public function doStuff()
{
// myExceptionHandler handles this exception
//throw new Exception("Exception from " . __METHOD__);
}
public function __destruct()
{
// default exception handler
throw new MyException();
}
}
$myclass = new MyClass();
$myclass->doStuff();
