How to delete duplicate data as per key value using PHP

Question

I need some help. I need to remove duplicate data as per key value using PHP. I am explaining my code below.

$orginalArr = array(
  array("id"=>1,"name"=>"Raj"),
  array("id"=>1,"name"=>"Raj"),
  array("id"=>2,"name"=>"Ram"),
  array("id"=>2,"name"=>"Ram"),
  array("id"=>3,"name"=>"Rahul")
);
echo json_encode($orginalArr);

Here I need to remove the data as per id, meaning if id value is same then one set of data will be removed. Please help me.

Just iterate through values and push it to the new array.
Example:

<?php
$orginalArr=array(array("id"=>1,"name"=>"Raj"),array("id"=>1,"name"=>"Raj"),array("id"=>2,"name"=>"Ram"),array("id"=>2,"name"=>"Ram"),array("id"=>3,"name"=>"Rahul"));

$newArray = array(); 

foreach ( $orginalArr as $arr )
    $newArray[$arr['id']] = array(
        'id' => $arr['id'], 
        'name' => $arr['name']); 



echo json_encode(array_values($newArray));
?>
