在PHP数组中组合相同的值

Question

我很难破解。

我有这个数组的电子邮件：

Array ( 
[0] => 9000@domain.com 
[1] => hasseris@domain.com 
[2] => storcenter@domain.com 
[3] => osteraa@domain.com 
[4] => vejgaard@domain.com 
[5] => gistrup@domain.com 
[6] => storvorde@domain.com 
)

和具有表单ID的此数组：

Array ( 
[0] => 1a21f6b7-8025-4724-b983-14745823ede1 
[1] => 4c8a63c0-4650-4884-b83c-70054f538ec2 
[2] => 148c1886-6674-45f3-9665-748bb6a34f4c 
[3] => 02fc3795-9457-4b02-91da-7d4b63eac1c0 
)

并通过此foreach，我遍历数组中的每个邮件以创建完整的JSON对象

foreach($mails_array as $key => $value) {

    foreach($formIds as $form) {

         $branchArray = array(
                   "FormIds" => [''.$form.''],
                   "Conditions" => array("sendto" => $value),
                   "From" => $date_from,
                   "To" => $date_to,
                   "Days" => ''
               );

         array_push($array, $branchArray);
    }  
}

$json = json_encode($array);
$string = preg_replace('/"([^"]+)"\s*:\s*/', '$1:', $json);

这将创建此json，该json用于调用API以根据条件（sendto）返回X表单上的提交数量：

[{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"9000@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"9000@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"9000@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"9000@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"hasseris@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"hasseris@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"hasseris@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"hasseris@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"storcenter@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"storcenter@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"storcenter@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"storcenter@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"osteraa@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"osteraa@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"osteraa@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"osteraa@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"vejgaard@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"vejgaard@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"vejgaard@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"vejgaard@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"gistrup@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"gistrup@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"gistrup@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"gistrup@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["1a21f6b7-8025-4724-b983-14745823ede1"],Conditions:{sendto:"storvorde@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["4c8a63c0-4650-4884-b83c-70054f538ec2"],Conditions:{sendto:"storvorde@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["148c1886-6674-45f3-9665-748bb6a34f4c"],Conditions:{sendto:"storvorde@domain.com"},From:"2016-03-23",To:"today",Days:""},{FormIds:["02fc3795-9457-4b02-91da-7d4b63eac1c0"],Conditions:{sendto:"storvorde@domain.com"},From:"2016-03-23",To:"today",Days:""}]

其中，FormIds是具有提交形式的特定表单的GUID。 条件中的“发送至”是我要在特定表单上提交的所有邮件。

因此，举例来说，我尝试将所有提交的所有4种表单都发送到9000@domain.com

上面的json返回此值，其中数字为条件下的提交：

{
  "arr": [
    1,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    1,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0,
    0
  ]
}

因此，我知道返回的JSON中的前4个项目（4个表单id）是9000@domain.com（1,0,0,0），接下来的4个是hasseris@domain.com（0,0,0 ，0）等

现在我的问题是我想将邮件数组和返回的json组合成一个简单的json，可以与电子邮件地址和提交总数一起输出。 应当将具有相同“ sendto”的4个表单合并，以便将在4个表单上找到的9000@domain.com的条件合并为一个项目，并在这4个表单上提交总数。

就像是：

{"landingPageData":[{"landingPage":{"landingPageMail":"9000@domain.com","landingPageLeads":"1"}},{"landingPage":{"landingPageMail":"hasseris@domain.com","landingPageLeads":0}},{"landingPage":{"landingPageMail":"storcenter@domain.com","landingPageLeads":"1"}},{"landingPage":{"landingPageMail":"osteraa@domain.com","landingPageLeads":"0"}},{"landingPage":{"landingPageMail":"vejgaard@domain.com","landingPageLeads":"0"}},{"landingPage":{"landingPageMail":"gistrup@domain.com","landingPageLeads":"-"}},{"landingPage":{"landingPageMail":"storvorde@domain.com","landingPageLeads":"0"}}],"totalLeads":2})

Answer 1

您可以遍历$mails_array并使用array_sum( array_slice() )小计求和：

$json = '{"arr":[1,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]}';

$data = json_decode( $json )->arr;
$result = array( 'landingPageData'=>[], 'totalLeads'=>0 );

foreach( $mails_array as $key => $email )
{
    $subTot = array_sum( array_slice( $data,$key*count( $formIds ), count( $formIds ) ) );
    $result['landingPageData'][] = array
    (
        'landingPage' => array
        (
            'landingPageMail'  => $email,
            'landingPageLeads' => $subTot
        )

    );
    $result['totalLeads'] += $subTot;
}

$result = json_encode( $result );

echo $result;

将打印（美化）：

{
    "landingPageData": [
        {
            "landingPage": {
                "landingPageMail": "9000@domain.com ",
                "landingPageLeads": 1
            }
        },
        {
            "landingPage": {
                "landingPageMail": "hasseris@domain.com ",
                "landingPageLeads": 0
            }
        },
        {
            "landingPage": {
                "landingPageMail": "storcenter@domain.com ",
                "landingPageLeads": 1
            }
        },
        {
            "landingPage": {
                "landingPageMail": "osteraa@domain.com ",
                "landingPageLeads": 0
            }
        },
        {
            "landingPage": {
                "landingPageMail": "vejgaard@domain.com ",
                "landingPageLeads": 0
            }
        },
        {
            "landingPage": {
                "landingPageMail": "gistrup@domain.com ",
                "landingPageLeads": 0
            }
        },
        {
            "landingPage": {
                "landingPageMail": "storvorde@domain.com ",
                "landingPageLeads": 0
            }
        }
    ],
    "totalLeads": 2
}

这是核心线：

$subTot = array_sum( array_slice( $data, $key*count( $formIds ), count( $formIds ) ) );

将当前的mails_array密钥乘以$formIds我们可以获得当前元素的起始$data密钥，然后我们可以从$data仅提取与当前电子邮件相关的值，并使用array_sum()对其求和。 总和被添加到一个新的landingPageData孩子和totalLeads值由它递增。
