数组的特殊工作

Question

我想用 PHP 数组做点什么。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，我想通过一个函数保存 message,id,from->name,created_time。我试图编写一个 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。你能告诉我怎么做吗？

Answer 1

对象的属性使用'->' 操作符访问（除非你实现了ArrayAccess 接口）。你应该像这样得到你的发件人姓名：

$var[0]->from->name

您可以选择将其转换为数组：

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

Answer 2

假设您将整个数组保存为变量$array，请尝试：

$array[0]->from->name;

你的函数可能看起来像这样：

for ($i = 0; $i < $inputArray.count(); $i++) {
  $message = $inputArray[$i]->message;
  $id = $inputArray[$i]->id;
  $name = $inputArray[$i]->from->name;
  $created = $inputArray[$i]->created_time;

  // Store the record as you want.
}

// Alternatively, a foreach loop
// See: http://php.net/manual/en/control-structures.foreach.php
foreach ($inputArray as $entry) {
  $message = $entry->message;
  $id = $entry->id;
  $name = $entry->from->name;
  $created = $entry->created_time;

  // Store the record as you want.
}
