@ is not convenient since it turns off error reporting for all errors. I don't know how many times I've silenced a notice and got a blank page in my face as a "thank you for accidentally silencing that fatal error too".
"Silent" is reserved for the purpose of the silence operator though @ so using that as a keyword for something else would be confusing. It just struck me that the ~real~ problem is that sometimes you want array access that should define undefined indexes as being null (a good placeholder for this purpose). How about (instead of the previously proposed ?? and isnotempty and whatnot) simply changing the "array access syntax" to simply allow an optional "?" operator at the end signaling that the condition where the index isn't defined isn't unexpected? For example: $value = isset($arr["foo"])? $arr["foo"]: null; $value = isset($arr[$foo])? $arr[$foo]: null; would be replaced with: (respectively) $value = $arr["foo"?]; $value = $arr[$foo?]; it would also worked chained: $value = $arr["foo"?]["bar"]["baz"?] (if [foo] doesn't exist value will be null.. if [foo] exists [foo][bar] is expected to exist but [foo][bar][baz] may or may not exist... if not, value will once again be null) This way it would only apply to array access which was a +1 for some. This could also be extended too replace null with something different (by allowing an expression after the "?" like "null" or "foo" . "bar") but I think careful use-case research should be done to determine if it's really needed first... I realize this partially collides with the use of ? so it would be more difficult to implement but it's far from impossible.. it just requires a little ahead-parsing in brackets [] to know if the "?" is a ternary if or if it's a "not exists is not undefined" operator (is the : missing or not?). Otherwise "??" could simply be used instead or a completely different operator... ~Hannes On 11 April 2011 04:47, Stas Malyshev <smalys...@sugarcrm.com> wrote: > Hi! > > @. >> > > Note however it does not exactly "turn off" the warning, only changes it to > not reported.
