Description:
------------
The function error_get_last() ignores the silence operator. Functions such as set_error_handler() received 0 as the value for the error type when the silence operator is used on the expression that triggered the error. However, error_get_last() does not.

This is rather inconsistent and makes it impossible to ignore errors when using error_get_last() for error handling (e.g. in a registered shutdown function).

Test script:
---------------
php -r '@1/0; print_r(error_get_last());'

Expected result:
----------------
PHP Warning:  Division by zero in Command line code on line 1
Array
(
    [type] => 0
    [message] => Division by zero
    [file] => Command line code
    [line] => 1
)

Actual result:
--------------
PHP Warning:  Division by zero in Command line code on line 1
Array
(
    [type] => 2
    [message] => Division by zero
    [file] => Command line code
    [line] => 1
)

That's how it's supposed to work. When suppressing errors you still may want to retrieve information about it.

Thank you. I seems as though I was mistaken with the return value of error_reporting() when using a custom error handler. There does not seem to be any possibility of checking if the silence operator was used when using error_get_last() though (e.g. in a shutdown handler).

Even its not a bug, its a missing feature. It would be really nice to know if an error was suppressed.

I'd like to echo the request for a way to check if the suppression operator was used. Perhaps it could be added as a key in the array returned by error_get_last?

E.g.

'suppressed' => true

Also, a related issue: the fact that error_get_last ignores the error_reporting level should be added to the documentation for both pages. Currently, this fact exists in a user comment on http://php.net/manual/en/function.error-get-last.php. But it should be noted officially, since many people don't read through the user comments.
