我需要在一个数组中合并值。我有这样的启动值：

Array  (
    [row] => Array
       (
         [0] => Array 
            (
             [personalnr] => 824
             [brutto] => 1000
             [netto] => 0
             [notiz] => 0
            )
         [1] => Array 
            (
             [personalnr] => 824
             [brutto] => 1000
             [netto] => 0
             [notiz] => 1
            )
         [2] => Array 
            (
             [personalnr] => 824
             [brutto] => 1000
             [netto] => 0
             [notiz] => 3
            )
       )
 )

问题在于row[0]，row[1]，row[2]具有相同的[personalnr]，[brutto]，[netto]。 [notiz]每行都不同。让我们说在我的数组中我有400 [rows]。一行重复4次，但每次只有不同的[notiz]。我需要只有100个[rows]，但每个 - 需要列[notiz] 4次（[notiz_1] [notiz_2] [notiz_3] [notiz_4]。最终金额[rows]的结果是100。

Array (
     [row] => Array 
     (
        [personalnr] => 824
        [brutto] => 100
        [netto] => 0
        [notiz] => array 
           (
             [1] = > 1
             [2] = > 2
             [3] = > 3

           )
     )
)

就像有人说过我试过的那样：

foreach ($value as $rownr => $dane) {
        $nrwiersza = $rownr;
        $test[$nrwiersza]['personalnr'] = $dane['personalnr'];
        $test[$nrwiersza]['std'] = $dane['std'];
        $test[$nrwiersza]["notiz"][] = $dane['notiz'];


    }

但是数组$test仍有400行。如何使用密钥[personalnr]，[brutto]，[netto]填充它，并将每个[notiz]放入[notiz_1]，[notiz_2]，[notiz_3]， [notiz_4]。

Answer 1

这是很多foreach循环，但这也可以让你找到你想要的东西而且密钥不是硬编码的：

// This is the final array, so set here.
$new    =   array();
// This is how many are in a group
$reset  =   3;
// This is the starting number for the counter
$i      =   1;
// The starting number for the group(s)
$a      =   1;
// Loop main row
foreach($array['row'] as $row) {
    // Loop through each key
    foreach($row as $key => $value) {
        // If the array is not set, assign value
        if(!isset($new[$a][$key]))
            $new[$a][$key]  =   $value;
        else {
            // If the array is set already but is a string
            if(!is_array($new[$a][$key])) {
                // If the current value doesn't equal stored value,
                // make an array with stored value and new value
                if($new[$a][$key] != $value) {
                    $new[$a][$key]  =   array($new[$a][$key],$value);
                }
            }
            // If array, make new value
            else
                $new[$a][$key][]    =   $value;
        }
    }
    // Reset the increment value
    // Also advance group number
    if($i == $reset) {
        $i = 0;
        $a++;
    }

    $i++;
 }
// Show new
print_r($new);

应该给你：

Array
    (
        [0] =>Array
            (
                [personalnr] => 824
                [brutto] => 1000
                [netto] => 0
                [notiz] => Array
                    (
                        [0] => 0
                        [1] => 1
                        [2] => 3
                    )
            )
        [1] =>Array
            (
                [personalnr] => 822
                [brutto] => 2000
                [netto] => 0
                [notiz] => Array
                    (
                        [0] => 1
                        [1] => 3
                        [2] => 4
                    )
            )
    )

Answer 2

看起来几乎是正确的。问题是这样的：当你做的时候

foreach ($value as $rownr => $dane) {

$rownr是原始数组中的数字键。然后你做

$nrwiersza = $rownr;

所以$nrwiersza现在具有该键的值。然后使用$nrwiersza作为结果数组中的键。这意味着它必须始终与原始数组具有相同的行数，因为$nrwiersza是唯一的。您需要使用行中的非唯一值作为键。所以不要设置

$nrwiersza = $rownr;

您可以将此用作密钥。

$nrwiersza = $dane['personalnr'];

那应该解决它。

foreach ($value as $rownr => $dane) {

    // Change the key here
    $nrwiersza = $dane['personalnr'];

    $test[$nrwiersza]['personalnr'] = $dane['personalnr'];
    // add the other keys from your original array
    $test[$nrwiersza]['brutto'] = $dane['brutto'];
    $test[$nrwiersza]['netto'] = $dane['netto'];
    $test[$nrwiersza]["notiz"][] = $dane['notiz'];
}

Answer 3

只需使用personalnr作为密钥，然后创建或附加条目，具体取决于该数字是否已存在：

$array //your array
$finalArray = array();    
foreach ($array["row"] AS $data){
   if (isset($finalArray[$data["personalnr"]])){
      //append notiz
      //append to array
      $finalArray[$data["peronalnr"]]["notiz"][] = $data["notiz"];
   }else{
      //transform notiz to an array
      $data["notiz"] = array($data["notiz"]);

      //Create that entry with $data["notiz"] now beeing an array.
      $finalArray[$data["personalnr"]] = $data;
   }
}

untestet，但是像这样。

应该导致：

Array  (
         [824] => Array 
            (
             [personalnr] => 824
             [brutto] => 1000
             [netto] => 0
             [notiz] => Array (
                 [0] => 0, 
                 [1] => 1 , 
                 [2] => 3 
              ) 
            )
       )

另外，“我肯定不得不在这里......”不能服务器在这里为你做重任？您所描述的内容可以通过服务器端的适当SQL查询来轻松处理。因此，是否可以设计系统以便客户端向服务器发送适当的请求，并作为响应接收不需要进一步“JavaScript重写？”的回复。
