Remove duplicate data based on postID - php

Question

I have an array which is as follows:
Array
(
[0] => Array
(
[postId] => 105
[postTitle] => Test
[postNonArray] => Subzero
[postDesc] => Array
(
[0] => Array
(
[para] => Subzero
[align] => L
)
)
[postDate] => 25.08.2016
[postTime] => 13:44
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472112857.png
[postVideo] =>
)
[1] => Array
(
[postId] => 106
[postTitle] => Test 2
[postNonArray] => Test
[postDesc] => Array
(
[0] => Array
(
[para] => Test
[align] => L
)
)
[postDate] => 26.08.2016
[postTime] => 18:08
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472215085.jpg
[postVideo] =>
)
[2] => Array
(
[postId] => 106
[postTitle] => Test 2
[postNonArray] => Test
[postDesc] => Array
(
[0] => Array
(
[para] => Test
[align] => L
)
)
[postDate] => 26.08.2016
[postTime] => 18:08
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472215085.jpg
[postVideo] =>
)
)
As you can see, there is two post details with postId=106;
How can I remove the redundant data from the array based on postId?
The project is on PHP.

Answer 1

I think this is what you are trying to achieve:-
$array = array_map("unserialize", array_unique(array_map("serialize", $array)));
echo "<pre/>";print_r($array);
Check output(whole code with your original array):- https://eval.in/630678
Note:- It will remove the duplicate values (so whole duplicate array will gone as you asked in comment)

Answer 2

I would suggest loop like the one below. It will go through all the elements from $your_array_name and will make an unique array of id where we will store the postIds. We will also check if there are duplicated in the $unique_ids array, and if so we will remove that duplicate element.
$unique_ids = array();
foreach($your_array_name as $key => $value){
//check if the postId is in the array of the unique ids
if(!in_array($value['postId'], $unique_ids)()){
array_push($unique_ids,$value['postId']); //if it is not - push it there
} else {
unset($your_array_name($key)); //if it is - remove the whole element from the array
}
}

Answer 3

You will need to loop the data and create a new array with unique values so here you go:
$ShowNewArray = array();
foreach($array as $key => $value){
if(!array_key_exists('postId', $ShowNewArray)){
$ShowNewArray[$value['postId']] = $value;
}
}
print_r($ShowNewArray);
Hope it will help you.
