Question

I am using ErrorException as my central error handling function for Errors and Exception:

Example:

set_error_handler('my_error_handler');
set_exception_handler('my_exception_handler');    

function my_error_handler ($errno, $errstr, $errfile, $errline)
{
    my_exception_handler(new ErrorException($errstr, 0, $errno, $errfile, $errline));
}

function my_exception_handler ($e)
{   
    echo $e->getSeverity();
    echo $e->getCode();
    echo $e->getMessage();          
}

Now it appears $e->getSeverity(); is only present in ErrorException and not in the default Exception;

Because when I throw new Exception('test'); I get a Fatal error: Call to undefined method Exception::getSeverity().

But when I throw new ErrorException('test'); it works as expected.

This seems logical but is there a way I can still use throw new Exception('test'); without getting the Fatal Error? Most third-party libraries use Exception (not ErrorException) so it will be problematic when a third-party exception occurs, it will cause Fatal Error. How can I solve this?

You can check if the caught exception is an ErrorException:

if ($e instanceof ErrorException) {
    echo $e->getSeverity();
} else {
    // no getSeverity() available
}
