在数组PHP中合并重复项[关闭]

Question

I have an array generated daily that will have duplicate products in it.

[0] => Array
    (
        [product_id] => 85
        [name] => Widescreen Espresso v6.1
        [quantity] => 1
    )

[1] => Array
    (
        [product_id] => 85
        [name] => Widescreen Espresso v6.1
        [quantity] => 2
    )

[2] => Array
    (
        [product_id] => 114
        [name] => Panama Esmerelda Diamond Mountain
        [quantity] => 1
    )

I want to find duplicate products and total them up in an array that would look like this:

[0] => Array
    (
        [product_id] => 85
        [name] => Widescreen Espresso v6.1
        [quantity] => 3
    )

[1] => Array
    (
        [product_id] => 114
        [name] => Panama Esmerelda Diamond Mountain
        [quantity] => 1
    )

UPDATE:

I didn't want to remove the duplicates I want to merge duplicates so that the quantity of the product is added together. I managed to work a solution to it with the help of Meenesh Jain's answer below.

           $final_array = array();
           foreach($order_data as $item => $item_value) {
               $pid = $item_value['product_id'];
               if(!isset($final_array[$pid])) {
                 $final_array[$pid] = $item_value;
               } else {
                 $final_array[$pid]['quantity'] += $item_value['quantity'];
               }
            }
            print_r(array_values($final_array));

You can do it with mysqli

OR

you can apply a custom method on your array

 $temp_array = $new_array = array();
 foreach($array as $key => $arr_values){
   if(!in_array($arr_values['product_id'], $temp_array)){
         array_push($temp_array, $arr_values['product_id']);
         array_push($new_array,$array[$key]);
   } 
  } 

// this code will do the trick
