php - 数组的特殊工作

Question

我想用 PHP 数组做一些事情。我写了一个函数来做一些我会说的事情。我的输入数组是:

Array
(
    [0] => stdClass Object
        (
            [message] => Automated XML Site Map Generator
http://pastebin.com/xjJe38dp
            [id] => 103114753133019_371405176303974
            [from] => stdClass Object
                (
                    [id] => 735588533186829
                    [name] => Mohammad Mostafa Shahreki
                )

            [created_time] => 2013-04-26
            [updated_time] => 2013-04-26
        )

    [1] => stdClass Object
        (
            [message] => Simple but powerful DB class
http://pastebin.com/1qgxUrwX
            [id] => 103114753133019_371404696304022
            [from] => stdClass Object
                (
                    [id] => 735588533186829
                    [name] => Mohammad Mostafa Shahreki
                )

            [created_time] => 2013-04-26
            [updated_time] => 2013-04-26
        )

    [2] => stdClass Object
        (
            [message] => Convert Existing DB to Unicode
http://pastebin.com/pHu08cPs
            [id] => 103114753133019_371404609637364
            [from] => stdClass Object
                (
                    [id] => 735588533186829
                    [name] => Mohammad Mostafa Shahreki
                )

            [created_time] => 2013-04-26
            [updated_time] => 2013-04-26
        )

    [3] => stdClass Object
        (
            [message] => thanks mosthafa ,,,, for adding me to this group
            [id] => 103114753133019_103333343111160
            [from] => stdClass Object
                (
                    [id] => 10155092057165556
                    [name] => HalF PixeL
                )

            [created_time] => 2011-10-11
            [updated_time] => 2011-11-21
        )
)

我想将每个数据保存在我的 MySQL 数据库中。例如，我想通过函数保存 message,id,from->name,created_time 。我尝试编写一个 foreach 循环，但找不到添加 from->name 的方法，它是一个 stdClass，不能与 ['from']['name'] 一起使用。你能告诉我该怎么做吗？

对象的属性通过“->”运算符访问(除非您实现 ArrayAccess 接口(interface))。您应该像这样获取发件人姓名:

$var[0]->from->name

您可以选择将其转换为数组:

$from = (array) $var[0]->from;
echo $from['name'];
