Differentiate Array base on Value And Sum Of Array in Laravel - php

Question

I have array and first of all I want to differentiate base on site(key) and site is not limited to 1 or 2
And then sum of opening balance and closing balance of site
like all site(888) total_balance = opening_balance + closing_balance
(999) total_balance = opening_balance + closing_balance
"games": [
{
"id": 240,
"user_id": 1,
"site": "888",
"opening_balance": 5,
"closing_balance": 6
},
{
"id": 243,
"user_id": 1,
"site": "999",
"opening_balance": 3,
"closing_balance": 4
},
{
"id": 244,
"user_id": 1,
"site": "888",
"opening_balance": 5,
"closing_balance": 6
},
And want output like
(site => 888, total_balance => 22 , site => 999, total_balance => 7
(it could b string))
And code I tried:
{
$collection = collect(Site::all())->map(function($item , $key){
return $item["name"];
});
$record = Game::whereIn('site',$collection)->get();
dd($record);
/*$bySite = array();
foreach ($record as $key => $item) {
if(!isset($bySite[$item['site']])) {
$bySite[$item['site']] = array();
}
$bySite[$item['site']][$key] = $item;
}*/
}
after this code which I commented output is
but then I don't know how sum of this
{
"888": {
"0": {
"id": 240,
"user_id": 1,
"site": "888",
"opening_balance": 5,
"closing_balance": 6
},
"2": {
"id": 244,
"user_id": 1,
"site": "888",
"opening_balance": 5,
"closing_balance": 6
},
},
"999": {
"1": {
"id": 243,
"user_id": 1,
"site": "999",
"opening_balance": 3,
"closing_balance": 4,

Answer 1

You can achieve this using Laravel Collection.
$games = [
[
"id" => 240,
"user_id" => 1,
"site" => "888",
"opening_balance" => 5,
"closing_balance" => 6
],
[
"id" => 243,
"user_id" => 1,
"site" => "999",
"opening_balance" => 3,
"closing_balance" => 4
],
[
"id" => 244,
"user_id" => 1,
"site" => "888",
"opening_balance" => 5,
"closing_balance" => 6
]
];
$games = collect($games);
$games = $games->groupBy('site')->map(function($game, $key){
return [
'site' => $key,
'total_balance' => $game->sum('opening_balance') + $game->sum('closing_balance'),
];
})->values();
dd($games->toArray());
And the output would be,
array:2 [▼
0 => array:2 [▼
"site" => 888
"total_balance" => 22
]
1 => array:2 [▼
"site" => 999
"total_balance" => 7
]
]

Answer 2

step
1. foreach ($collection)
2. sum the value and store in array like ($collection->sum('opening_balance'), ($collection->sum('closing_balance')
3. then sum the variable
4. stop loop
5. then $final = $final['site'] . " => " . $final['sum'];
