var_dump($ib);给我以下输出：

array (
  'data' => array (
    0 => array ( 
      'id' => '2015469353355_151',
      'from' => array ( 
         'name' => 'Aah',

$array["paging"]['next']

如果我们假设主数组被分配给变量$array

因为paging是主数组的索引，它本身也是一个数组。您可以使用它的索引来深入了解并获取您需要的信息。

$ib['paging']会给你 -

paging => array (
  'previous' => '...',
  'next' => '...',
)

然后下一步是深入到您再次返回到next索引的数组中。所以你最终得到的是一个在索引中指定索引的语句。

$ib['paging']['next'];

如果next参数也是一个数组，您甚至可以进一步向下使用另一个索引 -

paging => array (
  'previous' => '...',
  'next' => array(
     'url'=>'https://graph.facebook...'
  ),
)

// this will give us `'https://graph.facebook...'`
echo $ib['paging']['next']['url'];
