Summary: User-defined error handler run despite at sign (@)
error control operator
Status: Not a bug
Type: Bug
Package: *General Issues
PHP Version: 5.3.10

I guess it does, but this report is not about error_reporting, it is about the
@ error control operator.
According to the documentation of @, any error message that might be generated
by the expression will be "ignored". Either the PHP interpreter is changed so
that this becomes the case, or, if the current behavior is desired, the
documentation is adapted to reflect the actual semantics.
To be perfectly clear, I am not asking to change the de facto semantics. I am
only asking that whatever semantics is used by the implementation matches the
documented semantics.

It says, "however you are still able to read the current value of
error_reporting
and act appropriately" followed by "Of particular note is that this value will
be
0 if the statement that caused the error was prepended by the @ error-control
operator."
To me this says quite clearly that error_reporting will be 0 if the @ was used
and that your custom error handler can read this value and "act appropriately."

Rasmus, the part you quoted is about error_reporting() settings, it merely
mentions the error control operator.
My question was, could you quote where "http://www.php.net/set_error_handler
[...] explains that the user-defined error
handler should check the error_reporting level in order to comply with the '@'
if so desired"?

"error_reporting() settings will have no effect and your error handler will be
called regardless - however you are still able to read the current value of
error_reporting and act appropriately. Of particular note is that this value
will
be 0 if the statement that caused the error was prepended by the @
error-control
operator."

Thanks rasmus, but I do not see this explanation. Could you quote it?

This is very much by design and definitely won't be changed since that would
break all sorts of code. It is also explicitly documented at
http://www.php.net/set_error_handler which explains that the user-defined error
handler should check the error_reporting level in order to comply with the '@'
if
so desired.
