有什么方法可以让php在未设置/未定义的变量和数组索引等上中止?

Currently, PHP would trigger (and log if logging is enabled) E_NOTICE 'errors' when accessing undefined variables and array indexes. Is there a way to make it abort on these, so that I know I don't miss any. Frankly, IMO, far too often a script SHOULD abort on such condition anyway, as it will inevitably break something farther down the execution path. In all other cases there is the '@' operator, that's what it is for, right?

I know I can use a custom error handler and abort on any condition. In fact I do use one already, but I do have places where I trigger notices myself (granted, E_USER_NOTICE instead of PHP's own E_NOTICE), and I also always return false letting PHP's own internal handler do its job - logging and aborting on errors, continuing on everything else.

Then there are other cases where PHP produces E_NOTICE without me wanting to abort the script. Basically, there is no way for me to know if a particular E_NOTICE is a result of an unset variable or a totally harmless condition (which notices should be caused by anyway).

有没有人有一个整洁和非黑客的解决方案?有什么推荐的方法吗?

干杯。
