This will result in PHP reporting a warning every time an uninitialized variable is used, each bad file access, and other (mostly) harmless errors, but might also represent a potential attack vector.

设置更改后，每当使用未初始化的变量、进行错误的文件访问及发生其他（大多数）无害错误时，PHP 都会报告一条警告消息，但也存在这是一个潜在攻击矢量的可能性。

So, actually on Tuesday we'll see how to decide whether a vector field is a gradient or not, and if it is a gradient, how to find the potential function.

周二我们就知道，怎样确定一个场是不是梯度，如果确实是梯度的话，怎样算出势函数。

I want to find the potential for this vector field.

我想找出这个向量场的势函数。

But another potential vector for the spread of the flu that has recently been discussed in the media may be your smartphone.

FORBES: Can Your Smartphone Spread The Flu?

The bottom line is this: what infectious potential does your phone actually represent as a vector to spread the flu?
