执行自定义错误句柄后执行默认异常处理程序

In PHP I have built an error handler using set_exception_handler function. It is executing my custom exception handler. I want PHP to execute default exception handler too after executing my handler. Here is my code.

function handleException( exception $e){ 
    echo $e->getMessage(); 
    restore_exception_handler(); 
} 

set_exception_handler( 'handleException');

echo $e->getMessage() is executed but then the default PHP exception handler doesn't get executed even after using restore_exception_handler. So, How can I make it works?

you should trigger previous exception handler after restoring it

function handleException( exception $e){ 
    echo $e->getMessage(); 
    restore_exception_handler();
    throw $e; //This triggers the previous exception handler
} 

set_exception_handler( 'handleException');

The manual is clear about that:

Sets the default exception handler if an exception is not caught within a try/catch block. Execution will stop after the exception_handler is called.

There is no chance to run any code after that.

But however, you can just call it explicitly:

try {
    // some code that throws an Exception
} catch(Exception $e) {
    handleException($e);
    // .. run custom handler now
}

No need to use restore_exception_handler() here.
