Question

我从运行php代码得到以下输出，现在我想从以下数组中获取“url”字段，我该怎么做到？

Array (
    [data] => Array (
        [0] => Array (
            [id] => xxxxx
            [from] => Array (
                [id] => xxxxxx
                [name] => abc
            )
            [start_time] => 2012-04-28T07:49:17+0000
            [end_time] => 2012-04-28T07:49:17+0000
            [publish_time] => 2012-04-28T07:49:17+0000
            [application] => Array (
                [id] => 389407107765872
                [name] => Ki News Social Reader
            )
            [data] => Array (
                [article] => Array (
                    [id] => 10150703062718596
                    [url] => http://example.com
                    [type] => kinewssocialreader:article
                    [title] => story
                )
            )

提前致谢！

Answer 1

像任何其他数组一样索引它。查看print_r的实际来源比看到它们在一行中串联起来更有帮助。

$arr['data'][0]['data']['article']['url']

Answer 2

$url=$myArray['data'][0]['data']['article']['url']; //assuming $myArray is array

Answer 3

使用此

$array['data'][0]['data']['article']['url']

如果您的数组变量名为$ array。

Answer 4

如果要使用密钥访问阵列：

$array["key_name"] , $array[$key_name]

如果要使用元素顺序访问数组：

$array[0], $array[1]

如果选择的结果是数组，则可以继续使用[]更深入：

假设$ array [“key”]包含一个数组，并且该数组具有“another_key”键值;

$array["key"]["another_key"]

也会奏效。

Answer 5

假设我正确地读取数据结构，那就是：

$variableName['data'][0]['data']['article']['url']

其中 $ variableName 是顶级数组的名称。括号不平衡，所以我不能100％确定结构。

我把结构看成是这样的。如果这与您的结构匹配，则上面的命名将起作用。

Array ( 
  [data] => Array ( 
    [0] => Array ( 
      [id] => xxxxx 
      [from] => Array ( 
        [id] => xxxxxx 
        [name] => abc 
      ) 
      [start_time] => 2012-04-28T07:49:17+0000 
      [end_time] => 2012-04-28T07:49:17+0000 
      [publish_time] => 2012-04-28T07:49:17+0000 
      [application] => Array ( 
        [id] => 389407107765872 
        [name] => Ki News Social Reader 
      ) 
      [data] => Array ( 
        [article] => Array ( 
          [id] => 10150703062718596 
          [url] => http://example.com 
          [type] => kinewssocialreader:article [title] => story
        ) 
      )
    )
  )
)
