PHP - Merging two arrays into one array (also Remove Duplicates)

Question

Hi I'm Trying to merge two arrays and also want to remove duplicate values from final Array.

Here is my Array 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
)

And this is my array 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

)

I'm using array_merge for merging both arrays into one array. it is giving output like this

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

)

I want to remove these duplicate entries or can I remove these before merging... Pleas help.. Thanks!!!!!!!
