如何使用PHP从关联数组中读取值？
问题描述：
This is my sample associative array:
Array (
[0] => Array (
[Name] => ALCOIN
[BasePlugin] => HTTP
[Version] => 1
[Description] => Plugin for ALCO_IN operations
[ImagePath] => ./resources
[xip] => http://www.example.org/XIP
[xsi] => http://www.w3.org/2001/XMLSchema-instance
[schemaLocation] => http://www.example.org/XIP XIP.xsd
)
[1] => Array (
[xip:Action] => Array (
[@attributes] => Array (
[Name] => OfferActivationByOfferID
[Version] => 1.0
[ImagePath] => ./resources
)
)
)
)
In that array I need to get the BasePlugin value and the name attribute value.
这是我的样本关联数组： p>
Array（\ n [0] =＆gt;数组（
[名称] =＆gt; ALCOIN
[BasePlugin] =＆gt; HTTP
[版本] =＆gt; 1
[描述] =＆gt; ALCO_IN操作的插件
[ImagePath] =＆gt; ./resources
[xip] =＆gt; http://www.example.org/XIP
[xsi] =＆gt; http://www.w3.org/2001/XMLSchema- instance
[schemaLocation] =＆gt; http://www.example.org/XIP XIP.xsd
）
[1] =＆gt;数组（
[xip：Action] =＆gt;数组（
[@attributes] =＆gt;数组（
[名称] =＆gt; OfferActivationByOfferID
[版本] =＆gt; 1.0
[ImagePath] =＆gt; ./resources
）
）
）
）
）

在该数组中，我需要获取 BasePlugin code>值和名称 attribute code>值。 p >

Assuming you are assigned to $yourVar like:
$yourVar = Array (
[0] => Array (
[Name] => ALCOIN
[BasePlugin] => HTTP
[Version] => 1
[Description] => Plugin for ALCO_IN operations
[ImagePath] => ./resources
[xip] => http://www.example.org/XIP
[xsi] => http://www.w3.org/2001/XMLSchema-instance
[schemaLocation] => http://www.example.org/XIP XIP.xsd
)
[1] => Array (
[xip:Action] => Array (
[@attributes] => Array (
[Name] => OfferActivationByOfferID
[Version] => 1.0
[ImagePath] => ./resources
)
)
)
)
You would use:
echo $yourVar[0]["BasePlugin"];
echo $yourVar[1]["xip:Action"]["@attributes"]["Name"];
echo $yourVar[1]["xip:Action"]["@attributes"]["Version"];
echo $yourVar[1]["xip:Action"]["@attributes"]["ImagePath"];
答
It seems you might need this:
$basePlugin = $yourArray[0]['BasePlugin'];
$attributes = $yourArray[1]['xip:Action']['@attributes'];
