这是我从twitter API调用返回的数组的第一部分。我正在尝试提取[expanded_url]变量并将其存储到另一个数组中。我已经为[id]或[text]等顶级项目工作了，但我不确定如何访问更深层次的元素。

这是我用来访问和回显[id]的代码。我需要修改它以找到[expanded_url]
foreach($string['statuses'] as $items)
{
echo $items['id']."<br />";
}
一旦我能够在循环中对[expanded_url]进行微调，如果可能的话，我想将每个url存储到一个数组中！
这似乎在大多数情况下都有效，尽管有时确实会导致错误。
foreach($string['statuses'] as $items)
{
if($items['user']['entities']['url']['urls']['0']['expanded_url'] !="")
echo $items['user']['entities']['url']['urls']['0']['expanded_url']."<br />";
