As of PHP 5.4.11....



Instead of:



Output: Fatal error: Exception thrown without a stack frame in Unknown on line 0



This snippet:



<?php

function error_handler($code, $message, $file, $line)

{

    if (0 == error_reporting())

    {

        return;

    }

    throw new ErrorException($message, 0, $code, $file, $line);

}

function exception_handler($e)

{

    // ... normal exception stuff goes here

    print $undefined; // This is the underlying problem

}

set_error_handler("error_handler");

set_exception_handler("exception_handler");

throw new Exception("Just invoking the exception handler");

?>



Now returns:



Fatal error: Uncaught exception 'ErrorException' with message 'Undefined variable: undefined' in C:\Apache2\htdocs\error\test.php:13 Stack trace: #0 C:\Apache2\htdocs\error\test.php(13): error_handler(8, 'Undefined varia...', 'C:\Apache2\htdo...', 13, Array) #1 [internal function]: exception_handler(Object(Exception)) #2 {main} thrown in C:\Apache2\htdocs\error\test.php on line 13



So it appears that exceptions thrown within exception handler now bypass exception handler.
