this questin is asked many times but every one using same array but in my case i have 2 arrays consider i have 2 arrays
array1:3 [
10 => 900.0
20 => 450.0
30 => 600.0
]
array2:3 [
30 => 200.0
10 => 500.0
20 => 600.0
]
output should be
[900.0 - 500 = 400 // according to same id 10 = 10
450.0 - 600 = -150 // 20 = 20
600.0 - 200 = 400 // 30 = 30
]
in this array consider 10,20,30 are ids and next is value i want output where compare ever id and get difference example if (id1 = id2 ){ id1 => value - id2 => value }
i need help in that code which i already tried
$getsellerreport = SellerSellsReport::where('seller_id' , $seller_id);
$getunitdiff = $getsellerreport->pluck('unit')->toArray();// [0 => 75 1 => 500 => 100]
$getamountdiff = $getsellerreport->pluck('amount')->toArray(); // [0 => 11000 => 40 2 => 900]
$getproductdiff = $getsellerreport->pluck('product_id')->toArray(); // [0 => 39 1 => 242 => 23]
foreach($product_report as $preport){
$unit[] = $preport['unit'];// [0 => 75 1 => 25 2 => 100]
$amount[] = $preport['amount'];// [0 => 900 1 => 450 2 => 600]
$product_id[] = $preport['product_id'];// [0 => 23 1 => 242 => 39]
} // here we get array two values
above code get values with starting 0 key value and on below for() loop we can use product_id to compare both product id and get unit and amount but i dont know how i can do that can someone help me?
for ($i = 0 ; $i < sizeof($amount) ; $i++){
$unitdiff[] = $getunitdiff[$i] - $unit[$i];
$amountdiff[] = $getamountdiff[$i] - $amount[$i];
}
You could collect the arrays and use map, here is a sample to get you started:
$a = [
10 => 900.0,
20 => 450.0,
30 => 600.0,
];
$b = [
30 => 200.0,
10 => 500.0,
20 => 600.0,
];
$x = collect($a)->map(function($aItem, $index) use ($b) {
return $aItem - $b[$index];
});
dd($x); // yields [ 10 => 400.0, 20 => -150.0, 30 => 400.0 ]
