Description:
------------
I noticed in php 5.6.30 that all thrown Exception are output to log_error.

The only way i found to disable Output/logging this Exception, is to disable log_errors.

I expected, only uncatched Exception are outputed with a backtrace.

This makes using exception as internal Error handling not very usable. If log_error is disabled - no uncatched error is shown.
If enabled...  php commandline output exception , which are handled in the code by an try-Catch are logged. If log_error is redirected to an logfile - i think the logfile is spammed with unnecessary Errors.

Perhaps there should be an option, to only protocol unhandled Exceptions.


I found no documentation of this behavior.

Package: php5
Version: 5.6.30+dfsg-0+deb8u1

php -v 
PHP 5.6.30-0+deb8u1 (cli) (built: Feb  8 2017 08:50:21)


UPDATE:
if xdebug extension is disabled - output disapears. Make this sense ?


Test script:
---------------
<?php


try {
        throw new ErrorException("a");
 }
 catch (Exception $ex) {
         echo "catched and handle Error";
 }





Expected result:
----------------
catched

Actual result:
--------------
PHP ErrorException:  a in test.php on line 7
PHP Stack trace:
PHP   1. {main}() test.php:0
catched
