Php 动态获取数组的名称

我有一个如下所示的数组：

$example = [
             ['rendered'][0]['rendereditem1']
             ['rendered'][4]['rendereditem2 and more']
             ['rendered'][2]['rendereditem3']
]

现在我想用

foreach

进行迭代，以获得0,4,2的内容

通常我会写：

foreach($example as $value){
    print $value['rendered'][int which is the same everywhere];
}

---

但这显然不起作用，因为数组名称总是不同的……在这种情况下，我如何迭代？

只需添加第二个循环来迭代成员：

foreach($example as $value) {
  foreach($value['rendered'] as $key=>$item) {
    // Do what you want here, $key is 0,4,2 in your example
  }
}

对P尤其是这一部分[int，处处相同]是的；P尤其是这一部分[int，处处相同]
