我正在尝试返回一个“改变的”数组。

例如，我当前的数组如下所示: 代码:

    $filtered = array();
foreach($inBounds as $index => $columns) {
    foreach($columns as $key => $value) {       
    if(in_array($columns,$filtered)){
    }else{
    $filtered[$z] = $columns;
    $z = $z + 1;    
    }
}
}

数组

        [141] => Array

                [limit_lat] => 28
                [count] => 
            )
    [140] => Array
        (
            [id] => 1005

            [sizeIcon] => icon1
            [limit_lat] => 49
            [count] => 
        )

  )

现在我想计算重复项 ( [limit_lat] )，将它们从当前数组中删除，然后像下面的数组一样将它们放回一起:

这是重复清除后我需要的样子。

Array
 (
    [0] => Array
        (
            [id] => 1006
            [lat] => 51.28940600
            [lng] => 6.98730500
            [name] => fghfgh
            [date] => 2018-08-31 11:47:23
            [sizeIcon] => icon1
            [limit_lat] => 51
            [count] => 3
        )


    [1] => Array
        (
            [id] => 1009
            [lat] => 51.97811300
            [lng] => 7.83325200
            [name] => wer
            [date] => 2018-08-31 13:56:02
            [sizeIcon] => icon1
            [limit_lat] => 52
            [count] => 2
        )

    [2] => Array
        (
            [id] => 1011
            [lat] => 27.95195200
            [lng] => -82.46612500
            [name] => sdfsdf
            [date] => 2018-08-31 13:57:12
            [sizeIcon] => icon1
            [limit_lat] => 28
            [count] => 4
        )
    [3] => Array
        (
            [id] => 1005
            [lat] => 49.48240100
            [lng] => 0.28564500
            [name] => dsfsdf
            [date] => 2018-08-30 15:21:32
            [sizeIcon] => icon1
            [limit_lat] => 49
            [count] => 1
        )   

    )

现在我可以很好地计算它们，但我只能得到这个: 代码:

$data = array();
foreach($filtered as $cluster) {
    if(isset($data[$cluster['limit_lat']])) {
        $data[$cluster['limit_lat']]++;
    } else {
        $data[$cluster['limit_lat']] = 1;
    }
}

数组:

Array
(
    [51] => 3
    [52] => 2
    [28] => 4
    [49] => 1
)

我已经尝试了多种方法，但没有得到想要的结果。有人知道我如何才能让它工作吗？

谢谢， 丹尼斯

最佳答案

如果 limit_lat 是您所需要的，您可以使用 array_count_values 和 array_column。
Array_column 将所有 limit_lat 项过滤到一个一维数组中，array_count_values 将对它们进行计数。

$count = array_count_values(array_column($arr, "limit_lat"));

现在 $count 的输出与您的预期输出类似。

编辑:现在看到您也想删除重复项。

$count = array_count_values(array_column($arr, "limit_lat"));
// Remove duplicates
$nodupes = array_column($arr, Null, "limit_lat");

// Add count to array items.
foreach ($count as $key => $c){
     $nodupes[$key]['count'] = $c;
}
$nodupes = array_values($nodupes);

这应该可以，但我无法测试它。
如果你想要一个确定的代码 json_encode 或 var_export 你的数组，以便我们可以使用它。
