How to Take data from Explode and Check if same data

Question

I have case by equating the existing data

i Have 2 data with format like this

$data1 = "144|aku|1!!!122|dia|2";  data description "id|name|amount"

$data2 = "144|aku|1!!!211|dia|1";

there is the same data in 2 arrays, how to make the same data in the amount section can be added and unequal data will be inserted into the array

how to make the 2 arrays become like this

$data_result  = "144|aku|2!!!122|dia|2!!!211|dia|1";

this my full script

$data1 = "144|aku|1!!!122|dia|2";

$data2 = "144|aku|1!!!211|dia|1";


    $simpan_array = array();
    $array_status = array();
               // Pecah Array dari user dulu

               $array_code_user =  explode('!!!', $data1 );
               $jumlah_item_user = count($array_code_user) - 1;
               $x = 0;

               // Pecah Array dari lokal
               $array_cart_local   = explode('!!!',$data2 );
               $jumlah_cart_local  = count($array_cart_local) - 1;
               $j = 0;

                while( $x <= $jumlah_item_user ) {
                    $ambil_datacart_user = explode( '|', $array_code_user[$x] );

                        $idproduk_user   = $ambil_datacart_user[0];

                  $x++;      

                }

Answer 1

I loop the first array and call the output "result".
Then as I loop the second I see if the data exists in result array and it they do I add it to result else I create the new item.

$array1 = explode("!!!", $array1);
$array2 = explode("!!!", $array2);

Foreach($array1 as $val){
    List($id, $name, $amount) = explode("|", $val);
    $result[$id] = ['name' => $name, 'amount' => $amount];
}

Foreach($array2 as $val){
    List($id, $name, $amount) = explode("|", $val);

    If(isset($result[$id])){
        $result[$id]['amount'] += $amount;
    }Else{
        $result[$id] = ['name' => $name, 'amount' => $amount];
    }
}

I did not include the conversion back to your format.
It's a cute format with all the pipes and exclamation marks but I strongly encourage you to use json_encode().
That makes a string that can easily be decoded again without home made functions.
