PHP多维数组-创建和读取数据 [英] PHP Multidimensional Arrays - Creating and Reading Data

问题描述

我对多维数组有一点问题。我认为它们与JAVA中的不一样。例如;我创建了一个类似这样的数组；

I have a little problem with multidimensional arrays. I think they are not like those in JAVA. For instance; I have created a array something like this;

$myArray = array();

然后我尝试为它分配4个不同的数组，如下所示。

Then I try to assign 4 different arrays to it as following.

$myArray[0] = $newArray0;
$myArray[1] = $newArray1;
$myArray[2] = $newArray2;
$myArray[3] = $newArray3;

但是当我尝试从下面一行的单元格中读取数据时，

But when I try to read a data from a cell with following line,

$myArray[0][2];

我无法获得我想要的数据。你们能告诉我我在哪里弄错了吗？

I could not get the data what I was hoping for. Can you guys tell me where am I mistaken?

非常感谢！

推荐答案

您有一个正确的想法

$myArray = array();
$myArray1 = array("a","b","c");
$myArray2 = array("d","e","f");
$myArray3 = array("g","h","i");

$myArray[0] = $myArray1;
$myArray[1] = $myArray2;
$myArray[2] = $myArray3;

echo($myArray[0][2]);
