如何使用密钥获取数组的值？

Array
(
    Array
    (
        [customer_id] => 98
        [vender_id] => 4
        [first_name] => Arfan
        [last_name] => Ali
        [email] => arfan427@gmail.com
        [mobile_number] => 0303030
        [address] => this is a test address
        [password] => cc03e747a6afbbcbf8be7668acfebee5
        [device_token] => 0
        [created_at] => 2014-11-11 14:46:47
    )
    [status] => 1
    [msg] => customer has been founded
)

我可以使用

获得msg值

$msg = $customer['msg']

如何获得customer_id，vendor_id，first_name等的价值。

Answer 1

$customer_id = $customer[0]['customer_id']; // outputs 98

您需要通过其他键（数组的第0个元素）进行访问。此操作为您提供了另一个数组，您可以再次应用相同的逻辑（customer_id或此时）。

编辑：如果您对结构有控制权，我建议稍微更改一下，以防止由于使用基于数字的索引和基于字符串的索引而意外破坏：

Array
(
    [customers] => Array
    (
        [customer_id] => 98
        [vender_id] => 4
        ...
    )
    [status] => 1
    [msg] => customer has been founded
)

然后您可以通过$customer['customers'][0]['customer_id']

进行访问

Answer 2

$customer_id = $customer['customer']['customer_id']

Answer 3

实际上，要获得这些值，您必须这样做：

$customer_id = $customer[0]['customer_id'];
$vender_id = $customer[0]['vender_id'];
$first_name = $customer[0]['first_name']; 
$last_name = $customer[0]['last_name']; 
$email = $customer[0]['email']; 
$mobile_number = $customer[0]['mobile_number']; 
$address = $customer[0]['address']; 
$password = $customer[0]['password']; 
$device_token= $customer[0]['device_token']; 
$created_at= $customer[0]['created_at'];

因为第一个数组的键（偏移量）是0
