我无法从数组中获取特定值。我试过这个，但它不起作用。
$item1 = $this->request->post['banner_image'];
foreach($item1 as $k => $v)
{
if($k == 'top' && $v > 0)
{
echo $v.' - ';
}
}
我只需要获得一些值...例如我们[top]和[left]。
这是var_dump（$ _ POST）;

答案 0 :(得分：0)
更好地查看结果的方法是在var_dump之前先echo "<pre>";。这将允许您更好地了解数组的格式。我的猜测是，您正在搜索的$key是嵌入在更深层次的。如果您仍然无法解析它，请尝试编辑您的帖子，以便我们查看更好的格式化视图。很难看到，但尝试回显（没有for循环）$item1[1]['image']并查看是否有任何东西吐出来。我认为您感兴趣的值实际上在$item1[1]之内，而不仅仅是$item1。希望这是有道理的。
