从对象中获取价值

Question

我有以下对象，我试图从中获取一些值。这是一个片段：

WP_Query Object
(
    [query] => Array
        (
            [category_name] => Beauty
            [numberposts] => -1
            [posts_per_page] => 4
            [post_type] => post
            [post_status] => publish
            [orderby] => date
            [order] => DESC
            [paged] => 1
        )

    [query_vars] => Array

        (
            [category_name] => beauty
            [numberposts] => -1
            [posts_per_page] => 4
            [post_type] => post
            [post_status] => publish
            [orderby] => date
            [order] => DESC
            [paged] => 1
            [error] => 
            [m] => 
            [p] => 0
            [post_parent] => 
            [subpost] => 
            [subpost_id] => 
            [attachment] => 
            [attachment_id] => 0

我将如何获得：

[paged] => 1？

我尝试了以下方法，但都没有工作：

$category_query->paged; 
$category_query->query->paged; 

Answer 1

由于您必须遍历->的对象和[ ]的数组：

$category_query->query['paged']; 

因为$category_query是一个对象而query是一个数组。

Answer 2

试试：

$category_query->query['paged'];

Answer 3

这是一个数组的对象，所以你需要做..     $category_query->query['paged'];

使用->遍历对象和使用[ ]

的数组
