返回二维数组 [英] Returning a 2 dimensional array
问题描述
我正在尝试编写一个函数来返回一个二维数组，但是
它不起作用。我将返回值减少到1维并且测试了b $ b，以确保问题不在其他地方。当数组为1维时，它没有
问题。
我需要做些什么不同才能返回2
$一个函数的b $ b维数组？
I am trying to program a function to return a 2 dimensional array, but
it''s not working. I reduced the return value to 1 dimension and
tested that to make sure that the problem wasn''t elsewhere. It had no
problem when the array was 1 dimensional.
Is there something different I need to do in order to return a 2
dimensional array from a function?

是。在函数内创建一个二维数组。返回它。
这很简单：
函数get_2d_array（）{
返回数组（数组（ ））;
}
也许你的功能不是*创建一个2D阵列？

Yes. Create a 2-D array inside the function. Return it.
As simple as this:
function get_2d_array(){
return array(array());
}
Maybe your function is not *creating* a 2D array?

我确实创建了一个2D数组，我在函数中测试了它。
你的例子没有给出一个创建2D数组的例子，我不会在你的return语句中看到任何变量名。你可以
请扩展吗？

Your example doesn''t give an example of creating a 2D array and I
don''t see any variable names in your return statement. Could you
please expand on that?

是的。在函数内创建一个二维数组。返回它。
这很简单：
函数get_2d_array（）{
返回数组（array（））;

Parrot（me@myplace.com）TOP POSTED：
：我绝对创建了一个2D数组，我在函数中测试了它。
让我们看看代码。
：你的例子没有给出一个创建2D数组的例子，而且我看起来像是一个数组阵列给我。当你说2D数组时，也许你的意思是
。
：在你的return语句中看不到任何变量名。你可以吗？
：请扩展一下吗？
变量的名称与此有什么关系？他返回了一个php
" thing"这是一个数组数组。如果你愿意，你可以先将一个东西
分配给一个变量，然后使用该变量返回
的值。我承认我无法在
时刻测试，但很难想象它不会像我期望的那样工作......

Let''s see the code.
: Your example doesn''t give an example of creating a 2D array and I
It looks like an array of arrays to me. Perhaps you mean something else
when you say "2D array".
: don''t see any variable names in your return statement. Could you
: please expand on that?
What does the name of the variable have to do with this? He returns a php
"thing" which is an array of arrays. You could have assigned that "thing"
to a variable first if you wished, and then returned the value of the
thing by using the variable. I will admit I can not test that at the
moment, but find it hard to imagine it doesn''t work as I expect...
