使用PHP对数组中的类似数据进行分组

这是我的数组：

Array (
    [0] => Array (
        [NDC_Id] => 56
        [NDC_Date] => 2017-04-14
        [NDC_Type] => Night
        [NDC_Item] => Night
        [NDC_Rate] => 95.00
        [NDC_Quantity] => 1
        [NDC_Taxes] => 0
        [NDC_TaxesName] => 0
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
    [1] => Array (
        [NDC_Id] => 58
        [NDC_Date] => 2017-04-14
        [NDC_Type] => Item
        [NDC_Item] => Petit déjeuner
        [NDC_Rate] => 16.00
        [NDC_Quantity] => 2
        [NDC_Taxes] => 5.000,9.975
        [NDC_TaxesName] => TPS,TVQ
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
    [2] => Array (
        [NDC_Id] => 59
        [NDC_Date] => 2017-04-14
        [NDC_Type] => Item
        [NDC_Item] => Lit pour bébé
        [NDC_Rate] => 10.00
        [NDC_Quantity] => 1
        [NDC_Taxes] => 5.000,9.975
        [NDC_TaxesName] => TPS,TVQ
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
    [3] => Array (
        [NDC_Id] => 57
        [NDC_Date] => 2017-04-15
        [NDC_Type] => Night
        [NDC_Item] => Night
        [NDC_Rate] => 95.00
        [NDC_Quantity] => 1
        [NDC_Taxes] => 0
        [NDC_TaxesName] => 0
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
    [4] => Array (
        [NDC_Id] => 60
        [NDC_Date] => 2017-04-15
        [NDC_Type] => Item
        [NDC_Item] => Petit déjeuner
        [NDC_Rate] => 16.00
        [NDC_Quantity] => 2
        [NDC_Taxes] => 5.000,9.975
        [NDC_TaxesName] => TPS,TVQ
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
    [5] => Array (
        [NDC_Id] => 61
        [NDC_Date] => 2017-04-15
        [NDC_Type] => Item
        [NDC_Item] => Lit pour bébé
        [NDC_Rate] => 10.00
        [NDC_Quantity] => 1
        [NDC_Taxes] => 5.000,9.975
        [NDC_TaxesName] => TPS,TVQ
        [NDC_Provenance] => Room
        [NDC_ProvenanceRoomId] => 0
        [NDC_Status] => NotCharged
    )
)

当某些值等于且日期相同时，我试图对元素进行分组。

foreach ($array as $item) {
    $k = $item['NDC_Type'];

    if (!isset($result[$k])) {
        $result[$k] = $item;
    } elseif (
        ($i = $result[$k]) && 
        $item['NDC_Rate'] === $i['NDC_Rate'] && 
        $item['NDC_Item'] === $i['NDC_Item'] && 
        $item['NDC_Quantity'] === $i['NDC_Quantity'] &&
        $item['NDC_Taxes'] === $i['NDC_Taxes'] && 
        $item['NDC_TaxesName'] === $i['NDC_TaxesName'] && 
        $item['NDC_Status']=== $i['NDC_Status'] && 
        $item['NDC_Provenance'] === $i['NDC_Provenance'] && 
        $item['NDC_ProvenanceRoomId'] === $i['NDC_ProvenanceRoomId']
    ) {

        $result[$k]['NDC_Id'] .= ','. $item['NDC_Id'];

        $current_dates = explode(',', $result[$k]['NDC_Date']);
        $last_date = end($current_dates);
        if(date('Y-m-d', strtotime("{$last_date} +1 day")) === $item['NDC_Date']) {
            $result[$k]['NDC_Date'] .= ','. $item['NDC_Date'];
        } else {
            $result[$k. microtime()] = $item;
        }
    } else {
        $result[$k. microtime()] = $item;
    }
}

$result = array_values($result);

问题是Petit déjeuner和Night已分组但不是Lit pour bébé项目。

在这一行$result = array_values($result);之前，Lit pour bébé有一个奇怪的键名。我有[Item0.69717400 1494009685]，而且Lit pour bébé的密钥名称不同。也许这就是问题所在？

要回复Sahil Gulati，预期结果应如下：

Array (
    [0] => Array (
        [NDCId] => 56,57
        [NDCDate] => 2017-04-14,2017-04-15
        [NDCType] => Night
        [NDCItem] => Night
        [NDCRate] => 95.00
        [NDCQuantity] => 1
        [NDCTaxes] => 0
        [NDCTaxesName] => 0
        [NDCProvenance] => Room
        [NDCProvenanceRoomId] => 0
        [NDCStatus] => NotCharged
    )
    [1] => Array (
        [NDCId] => 58,60
        [NDCDate] => 2017-04-14,2017-04-15
        [NDCType] => Item
        [NDCItem] => Petit déjeuner
        [NDCRate] => 16.00
        [NDCQuantity] => 2
        [NDCTaxes] => 9.975,5.000
        [NDCTaxesName] => TVQ,TPS
        [NDCProvenance] => Room
        [NDCProvenanceRoomId] => 0
        [NDCStatus] => NotCharged
    )
    [2] => Array (
        [NDCId] => 59
        [NDCDate] => 2017-04-14,2017-04-15
        [NDCType] => Item
        [NDCItem] => Lit pour bébé
        [NDCRate] => 10.00
        [NDCQuantity] => 1
        [NDCTaxes] => 9.975,5.000
        [NDCTaxesName] => TVQ,TPS
        [NDCProvenance] => Room
        [NDCProvenanceRoomId] => 0
        [NDCStatus] => NotCharged
    )
)

我在这里使用简单的foreach来收集和分组项目

Try this code snippet here      

ini_set('display_errors', 1);
$string = '
{  
    "0"  : {  
        "NDC_Id"  :"56",

print_r(array_values($result));

)

解决方案2： Try this code snippet here

从此处更改您的代码： 

$k = $item['NDC_Type'];

的此： 

$k = $item['NDC_Type'].$item['NDC_Item'];
