PHP 错误报告和 mail()
目前,每当遇到任何问题时,set_error_handler()
都会抛出ErrorException
。此外,我在 -1
处得到了 error_reporting()
,因此错误索引数组会引发异常。
无论如何,这是我的错误/报告环境的粗略概述;在用于项目的过程中,PHP mail()
函数在我的 (Win7) 开发计算机上抛出错误,因为我没有安装邮件服务器。我尝试在它前面添加 @
前缀以将其关闭,但它仍然会触发错误,从而引发异常。我可以用 try{}
包装它,但我很好奇为什么它不会关闭。
为什么不闭嘴呢?
重申一下,我们几乎可以从等式中删除mail()
(据我所知);我只是想知道为什么 @
在这种情况下不能使用 mail()
或任何函数来完成它的工作。我只是认为 mail()
由于某种原因可能是特殊情况。

:
( ! ) ErrorException: mail() [function.mail]: 无法连接到“localhost”端口 25 的邮件服务器,请验证 php.ini 中的“SMTP”和“smtp_port”设置或使用 C 中的 ini_set() :\xampp\htdocs\dbc_relaunch_2-0-0\mf\handlers\api\mail\send.php 第 16 行
好吧,我已经走了与:
try{
mail($args);
catch(Exception $exception){
return $failure;
}
return $success;
而不是:
if(@mail($args)){
return $failure;
}
return $success;
一切都很好;我正在浏览 @Pheonix 链接的答案,但任何有简短回复的人都可以免费回答。
I've currently got set_error_handler()
throwing ErrorException
whenever anything is encountered. Furthermore, I've got error_reporting()
at -1
, so mis-indexing an array throws an exception.
Anyways, that being a cursory overview of my error/reporting environment; the PHP mail()
function is tossing errors on my (Win7) dev machine, during a process intended for a project, 'cause I don't have a mail server installed. I tried prefixing it with @
to shut it up, but it still triggers an error, and hence throws an exception. I could wrap it with try{}
, but I'm curious as to why it won't shut up.
Why won't it shut up?
To reiterate, we can almost remove mail()
from the equation (so far as I can tell); I just want to know why @
wouldn't do it's job under such a circumstance, with mail()
or any function. I just figured mail()
may be special case for some reason.
Thanks to our friend XDebug

( ! ) ErrorException: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\htdocs\dbc_relaunch_2-0-0\mf\handlers\api\mail\send.php on line 16
Alrighty, I've simply gone with:
try{
mail($args);
catch(Exception $exception){
return $failure;
}
return $success;
Rather than:
if(@mail($args)){
return $failure;
}
return $success;
And all is well; I'm browsing the answer @Pheonix linked, but anyone with a short order response as to why this is free to answer.

您能向我们展示您的错误处理程序吗?请注意,无论您的
error_reporting()
设置如何,即使您在函数前面添加@
,发生错误时都会调用您的处理程序。来自
set_error_handler()
的手册页。如果您不想针对由
@
前缀表达式引起的错误引发异常,则必须在处理程序中检查error_reporting()
的返回值。如果它返回零,则您正在处理一个被抑制的错误。Could you show us your error handler? Note that your handler will be called in case of an error, regardless of your
error_reporting()
setting and even if you prepend your function with an@
.From the manual page of
set_error_handler()
.If you don't want to throw exceptions for errors caused by an
@
prefixed expression, you'll have to check the return value oferror_reporting()
in your handler. In case it returns zero, you're dealing with a suppressed error.这是一篇有趣的文章

本页准确讨论了您想要实现的目标。
Here's an Interesting read
How do I catch a PHP Fatal Error
This page discusses exactly what you are trying to achieve.
这不是一个很好的答案,但我怀疑这是因为错误“消息”和错误“异常”不同。
php-exceptions-vs-errors 对此说了一些,但我发现的是,根据此评论,看来
set_error_handler()
实际上覆盖了@符号。也就是说,在处理异常时,try、catch 始终是最好的方法。
希望有一点帮助。
This isn't a very good answer, but I suspect it's because error 'messages' and error 'exceptions are not the same.
php-exceptions-vs-errors says a little about this, but what I found was that, as per this comment, it appears that
set_error_handler()
actually overrides the @ symbol.That said, try, catch is always the best approach when dealing with exceptions.
Hope that helped a little.
