PHP从数组内的数组中获取价值

Question

I'm sorry if this is a basic question but I'm just having trouble getting a value from an array within an array. Here is my code:

$data = Array (
    [message-count] => 1
    [messages] => Array (
         [0] => Array (
               [to] => 19998887777
               [message-price] => 0.00550000
               [status] => 0
               [message-id] => 0300000021B6B103
               [remaining-balance] => 18.59500000
               [network] => 31000
          )
     )
);

Then, for example, if I wanted to retrieve the message-id, I'm trying:

$messageID = $data['message-count']['messages']['message-id'];

That doesn't return anything so I know I'm missing something simple. Thank you in advance for any help!

Answer 1

message-count appears to be 1 . messages is an array of arrays, and that array contains message-id . To get the first message id, you would use

$data["messages"][0]["message-id"]

Answer 2

Note how I formatted your code snippet above. You forgot the [0] portion, so your assignment would be

$messageID = $data['messages'][0]['message-id'];
                              ^^^---forgot this

The ['message-count'] is not necessary, because it's not part of the "tree" branch you're going down.

Answer 3

你只是想念0

$data["messages"][0]["message-id"]
