多维关联数组（PHP） [英] Multidimensional Associative Array (PHP)

问题描述

我是新在PHP中的数组，我试图总结我的周围如何做一个多维关联数组的头脑。我想数组看起来像这样，当我使用的print_r：

 阵列（[0] =＆GT;数组（[警示] =＆GT;警告[邮件] =＆GT;测试））
 

相反，我得到这样的：

 阵列（[0] =＆GT;数组（[警示] =＆GT;数组（[邮件] =＆GT;测试）））
 

在code我使用的是这样的：

  $ alert_array =阵列（）;$ alert_array [] [警报] [电子邮件] =测试;
 

我想尝试这样的东西会的工作，但很明显，我的语法是有点过。我觉得我有点很正确的轨道上，但：？

  $ alert_array [] [[警报] [电子邮件] =测试;
 

您的帮助谢谢（对不起，如果这是超级基本的，我无法找到解决任何问题，这完全一致）！

解决方案

  $ alert_array =阵列（）;
$ alert_array [] =阵列（'警报'=＆GT;'警报'，'邮件'=＆GT;'测试'）;
...
后续代码var_dump（$ alert_array）;
 

在你的情况下，你必须指定键像这样：

  $ alert_array [$关键] [警报] =警告;
$ alert_array [$关键] [电子邮件] =测试;
 

您不得不与计数器循环了。

如果你使用PHP 5.4+，你可以使用短阵语法：

  $ alert_array = [];
$ alert_array [] = ['警报'=＆GT; 警报，电子邮件= GT; '测试'];
 

I'm new to arrays in PHP and am trying to wrap my mind around how to make a multidimensional associative array. I'd like the array to look like this when I use print_r:

Array ( [0] => Array ( [alert] => alert [email] => Test ) )

Instead I get this:

Array ( [0] => Array ( [alert] => Array ( [email] => Test ) ) )

The code I'm using is this:

$alert_array = array();

$alert_array[]["alert"]["email"] = "Test";

I thought trying something like this would work, but obviously my syntax is a bit off. I think I'm somewhat on the right track though?:

$alert_array[][["alert"]["email"]] = "Test";

Thank for your help (sorry if this is super basic, I couldn't find any questions that addressed this exactly)!

解决方案

$alert_array = array();
$alert_array[] = array('alert' => 'alert', 'email' => 'Test');
...
var_dump($alert_array);

In your case you'd have to specify key like so:

$alert_array[$key]["alert"] = "alert";
$alert_array[$key]["email"] = "Test";

You'd have to have a loop with counter too.

If you're using PHP 5.4+ you could use short array syntax:

$alert_array = [];
$alert_array[] = ['alert' => 'alert', 'email' => 'Test'];
