我的阵列就像这样

Array ( [0] => stdClass Object ( [ID] => 578 [post_author] => 1 [post_date] => 2011-01-18 07:23:17 [post_date_gmt] => 2011-01-18 07:23:17 [post_content] => Home WordPress is web software you can use to create a beautiful website or blog.

当我这样写的时候

$myposts = get_posts( $args );
$arrDt = (array) $myposts;
print_r($arrDt);

但我的问题是如何获取该对象数组中的值。

请帮忙。日Thnx 的print_r（$ arrDt）;

Answer 1

这只是普通的对象访问：

$obj = $arrDt[0];
echo $obj->ID;
echo $obj->post_author;
// etc.

但这取决于你想做什么。我建议看看get_posts示例。他们使用setup_postdata在当前上下文中加载帖子内容。如果你想显示帖子，这可能是更清洁的解决方案。

Answer 2

这很简单：

您有一个数组Array ( [0] => stdClass Object ( [ID]

这个数组有一个KEY，可以通过“[0]”识别（但可能存在更多的键））访问密钥：

foreach ( $arrDt as $value ): //Look, whe are inside the first key. (currently is '0').
   echo $value->ID;
   echo $value->post_author;
endforeach;

或者，如果你想将对象转换为数组（例如$ value ['ID']），你只需要这样：

    function objectToArray($obj)
    {
         if (is_object($obj)):
             $object = get_object_vars($obj); 
         endif;

         return array_map('objectToArray', $object); // return the object, converted in array.
    }

$objArray = objectToArray($arrDt);
print_r($objArray);

Answer 3

就我而言：

foreach ($returnedObject as $row) {
    $sub_array = '';
    $sub_array['ID'] = $row->data->ID;
    $sub_array['user_login'] = $row->data->user_login;
    $sub_array['display_name'] = $row->data->display_name;
    $sub_array['user_email'] = $row->data->user_email;
    $sub_array['user_registered'] = $row->data->user_registered;
    $main_array[] = $sub_array;
}

Answer 4

您可以使用 wp_get_recent_posts（）代替 get_posts（）。 wp_get_recent_posts（）函数返回一个普通数组而不是对象数组，然后使用foreach循环可以访问数组的任何值。

如何将对象转换为数组以获取数据？
