Hey there,

Every day I ran in some Problems wasting time to debug code, since the peoples are often using the error control operator (any software):

  http://de3.php.net/manual/en/language.operators.errorcontrol.php

It would be nice to see a php.ini directive, e.g. "error_controll_operators = 1|0", to disable or enable the silencing of php errors. 

Another old report (see #14192) was closed by jani@php.net, referring to some extension and xdebug. But, as controll operators itself are in the core, i think there SHOULD also be the option to disable/enable it...?

Thanks alot

Test script:
---------------
<?php
ini_set('error_controll_operators',0);
@anyNonExistingFunction();
?>

Expected result:
----------------
Fatal error: Call to undefined function anyNonExistingFunction() in /root/test.php on line 3


Actual result:
--------------
Empty Output
