阵列与相同SKU的总和值

Question

我从URL获取总销售物品，并返回包含'SKU'，'Date'，'Quantity'和'Total Price'的数组。 我想计算相同'SKU'的总数量并存储在新阵列中。 任何人都可以告诉我如何在PHP语言中做到这一点？

$url ="abc";     
<pre> 
$post_fields = array();      
$post_fields['EndDateUtc']=$end; 
$post_fields['StartDateUtc']=$start; 
$post_fields['TenantToken']=$TenantToken; 
$post_fields['UserToken']= $UserToken;   
$data_string = json_encode($post_fields);    
</pre> 
<pre> 
$curl_header = array(); 
$curl_header[] = 'Content-type: application/json'; 
$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $curl_header); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 180); 
curl_setopt($ch, CURLOPT_TIMEOUT, 180); 
$output = curl_exec($ch); 
curl_close($ch); 
$datr = json_decode($output, TRUE); 
print_r($datr); 

阵列输出： --------------

 

Array 
(
    [SoldItems] => Array 
     (
      [0] => Array 
       (
        [SKU] => 8273-Navy-M 
        [Date] => 2017-10-12 
        [Quantity] => 15 
        [TotalPrice] => 7685 
       ) 

      [1] => Array 
       (
        [SKU] => 2879-S-B-White-3XL 
        [Date] => 2017-10-12 
        [Quantity] => 2 
        [TotalPrice] => 298 
       ) 

      [2] => Array 
       (
        [SKU] => 8273-Navy-M 
        [Date] => 2017-10-12 
        [Quantity] => 2 
        [TotalPrice] => 298 
       ) 

      [3] => Array 
       (
        [SKU] => 2262-S-A-Black-2XL 
        [Date] => 2017-10-12 
        [Quantity] => 1 
        [TotalPrice] => 199 
       ) 
     ) 
) 

</pre> 

thank you so much. 

Answer 1

请试试这个：

$skuTotal = []; 

foreach($items['SoldItems'] as $item) { 
    if(isset($skuTotal[$item['SKU']])){ 
     $skuTotal[$item['SKU']] += $item['Quantity']; 
    }else{ 
     $skuTotal[$item['SKU']] = $item['Quantity']; 
    } 

} 

foreach($skuTotal as $sku => $total) { 
    echo "SKU " . $sku . " , Total " . $total." "; 
} 

Answer 2

你应该有这样的事情去了，这是未经测试，可能需要一些调整，以符合您的实际场景：

$totalsBySku = []; 

foreach($soldItems as $sale) { 
    $totalsBySku[$sale['SKU']] += $sale['Quantity']; 
} 

foreach($totalsBySku as $sku => $total) { 
     print "SKU " . $sku . " has a total quantity of " . $total; 
}
