如何使用foreach循环来获取这个数组 [英] how to fetch this array using foreach loop

问题描述

我有一个多维数组。该阵列是使用卷曲解析XML返回。当卷曲给我的输出我转换输出到数组使用$阵列=（阵列）simplexml_load_string（$查询）;和$阵列如下。现在，我想用foreach循环来获取这个数组和想要的一切，从这个阵列

i have a multidimensional array. the array is returned by parsing xml using curl. when curl gave me the output i converted the output into array using $array = (array) simplexml_load_string($query); and the $array is given below. Now i want to fetch this array using foreach loop and want everything from this array

Array
(
[Meta] => SimpleXMLElement Object
    (
      [Query] => php programming
      [ResultOffset] => SimpleXMLElement Object
            (
            )

      [NumResults] => 25
      [TotalResults] => 36839
    )

[Slideshow] => Array
       (
        [0] => SimpleXMLElement Object
            (
                [ID] => 1966058
                [Title] => title here
                [Description] => description here
                [Status] => 2
                [Username] =>usrname
                [URL] => url here
                [ThumbnailURL] => a url
                [ThumbnailSmallURL] => a url
                [Embed] => some embed code
    )
    [1] => SimpleXMLElement Object
            (
                [ID] => 1966058
                [Title] => title here
                [Description] => description here
                [Status] => 2
                [Username] =>usrname
                [URL] => url here
                [ThumbnailURL] => a url
                [ThumbnailSmallURL] => a url
                [Embed] => some embed code
    )

和继续

推荐答案

您可以检索元数据信息，而无需使用的foreach：

You can retrieve meta information without using foreach:

echo $array['Meta']->Query;
echo $array['Meta']->NumResults;

等等...

要获取幻灯片：

foreach($array['Slideshow'] as $slideshow)
{
    echo $slideshow->ID;
    echo $slideshow->Title;
    //-- and so on...
}
