Здравейте,  колеги някой може ли да ми кажи къде греша в тая задача всичко се изпълнява по условието а в judge 20 / 100.

тук е моя код  https://pastebin.com/rwunG0Cm

Orders

Write a program, which keeps information about products and their prices. Each product has a name, a price and its quantity. If the product doesn’t exist yet, add it with its starting quantity.

If you receive a product, which already exists increase its quantity by the input quantity and if its price is different, replace the price as well.

You will receive products names, prices and quantities on new lines. Until you receive the command "buy", keep adding items. When you do receive the command "buy", print the items with their names and total price of all the products with that name.

Input

  • Until you receive "buy", the products come in the format: "{name} {price} {quantity}".
  • The product data is always delimited by a single space.

Output

  • Print information about each product, following the format:
    "{productName} -> {totalPrice}"
  • Format the average grade to the 2nd decimal place.

Здравей, рефактор:

<?php
$shop = [];
while (($arrgs = readline()) !== "buy") {
    $arr = explode(" ", $arrgs);
    $articul = $arr[0];
    $price = $arr[1];
    $size = $arr[2];
    if (!key_exists($articul, $shop)) {
        $shop[$articul] = [0, 0];
    }
    $shop[$articul][0] = $price;
    $shop[$articul][1] += $size;
}
foreach ($shop as $key => $value) {
    $prices = $value[1] * $value[0];
    printf("$key -> %.2f" . PHP_EOL, $prices);
}
