require / include：常量与变量 [英] require/include: constant vs. variable

问题描述

我遇到了一个我无法解决的愚蠢问题。请看例子：


settings.php

Hi,

I am stuck with a silly problem which I cant resolve. Please look at the example:

settings.php

展开 | 选择 | Wrap | 行号

推荐答案

常量具有全局范围，而变量和数组则不包含。

A constant has global scope whereas variables and arrays do not.

常量具有全局范围，而变量和数组不具有全局范围。

A constant has global scope whereas variables and arrays do not.

如果在开头有inlude / require行怎么样？


values.class.php

What about having inlude/require line at the beginning?

任何包含settings.php的文件都可以看到数组，但函数或类是一个单独的实体。

如果你想要一个函数或类方法来查看它必须包含在函数中的数组。

但通常你只需将变量名作为参数传递给函数

Any file that includes settings.php can see the array, but a function or class is a seperate entity again.
If you want a function or class method to see the array it has to be included inside the function.
But normally you would simply pass the variable name in to the function as a parameter
