PHP - 将两个数组合并为一个数组(也删除重复项)

Question

您好，我正在尝试合并两个数组，并且还想从最终数组中删除重复值。

这是我的数组 1:

Array
    (
    [0] => stdClass Object
    (
    [ID] => 749
    [post_author] => 1
    [post_date] => 2012-11-20 06:26:07
    [post_date_gmt] => 2012-11-20 06:26:07
)

这是我的数组 2:

Array
(
[0] => stdClass Object
(
[ID] => 749
[post_author] => 1
[post_date] => 2012-11-20 06:26:07
[post_date_gmt] => 2012-11-20 06:26:07

)

我正在使用 array_merge 将两个数组合并为一个数组。它给出这样的输出

Array
(
[0] => stdClass Object
(
[ID] => 749
[post_author] => 1
[post_date] => 2012-11-20 06:26:07
[post_date_gmt] => 2012-11-20 06:26:07

[1] => stdClass Object
(
[ID] => 749
[post_author] => 1
[post_date] => 2012-11-20 06:26:07
[post_date_gmt] => 2012-11-20 06:26:07

)

我想删除这些重复的条目，或者我可以在合并之前删除它们吗...请帮助..谢谢!!!!!!!
