假设print_r（$ child）的结果是上面的，我想如何回显所有的tid和名字，我该怎么办？

foreach($child as $arr){
 foreach($arr as $key=>$vaule)
{
...

我不知道如何循环它们。

Answer 1

这应该为您打印数据。

foreach($child as $arr)
{

   echo 'Tid: ' . $arr->tid . ' and Name: ' . $arr->name . "\n";
}

您可能希望添加适当的HTML标记以对其进行格式化。

Answer 2

foreach($child as $arr)
{
   echo "output: ".$arr->tid." ".$arr->name;
}

Answer 3

您可以使用此php函数

将对象转换为数组

<?PHP

function object2array($data)
{
    if (is_array($data) || is_object($data))
    {
        $result = array();
        foreach ($data as $key => $value)
        {
            $result[$key] = object2array($value);
        }
        return $result;
    }
    return $data;
}

?>

使用此功能后，您可以使用此代码。

foreach($child as $arr)
{
    foreach($arr as $key=>$val)
    {
        if($key == "tid" || $key == "name")
        {
            // Here some code
        }
    }
}

如何输出结果？
