Bug description: error_reporting() interferes @ operator
Description:
------------
Setting a level of error reporting by a call to error_reporting(value)
function interferes with @ operator, ie. if the value is >0 error messages
are generated even within the scope of @ operator. This behavior
contradicts a statement made by manual about @ operator:
"When prepended to an expression in PHP, any error messages that might be
generated
by that expression will be ignored."
I would expect error messages to be ignored throughout an entire scope of
the @ operator regardless of operations performed there.
The following example is quite artificial, however there may be situations
one would like to have a function changing various configuration options
including error reporting level. When he or she also wants to disable all
warnings made by this function (or some of its caller) a problem arises.
Reproduce code:
---------------
<?
function f()
{
var_dump(error_reporting(E_ALL));
var_dump(error_reporting());
array_fill(-1,-1,-1); // deliberately invalid arguments
@f();
var_dump(error_reporting());
?>
Expected result:
----------------
int(0)
int(0)
int(2047)
Actual result:
--------------
int(0)
int(2047)
Warning: array_fill(): Number of elements must be positive in ...
int(2047)
