highcharts排序后php数组未设置/重置键

我有以下数组：

Array
(
[0] => Array
    (
        [0] => 2015-07-18
        [1] => 22 SSH
    )

[1] => Array
    (
        [0] => 2015-07-18
        [1] => 80 HTTP
    )

[2] => Array
    (
        [0] => 2015-07-18
        [1] => 3389 Remote Desktop
    )

[3] => Array
    (
        [0] => 2015-07-19
        [1] => 3389 Remote Desktop
    )

[4] => Array
    (
        [0] => 2015-07-19
        [1] => 3389 Remote Desktop
    )
)

以及以下函数，用于将数据转换为highcharts所需的格式/数组：

$result = array();
$result[0] = array();
$result[0][data] = array();
foreach ($stack_stats_timeline as $key => &$value) {
    if(!in_array($value[0], $result[0][data], true)) array_push($result[0][data], $value[0]);  
    $hash = $value[1];
    $result[$hash][name] = $value[1];
    $result[$hash][data][$value[0]] += 1;  
}   

到目前为止还不错。。。但问题是当我这么做的时候

$result = json_encode($result);
print_r($result); 

我明白了

[{"data":["2015-07-01","2015-07-02","2015-07-03"]},{"name":"8080 Unknown","data":{"2015-07-01":4,"2015-07-02":8,"2015-07-03":5}},{"name":"8118 Unknown","data":{"2015-07-01":3}},{"name":"3389 Remote Desktop","data":{"2015-07-01":14,"2015-07-02":52,"2015-07-03":65}},{"name":"80 HTTP","data":{"2015-07-01":3,"2015-07-02":12,"2015-07-03":7}},{"name":"8228 Unknown","data":{"2015-07-01":3}}]  

当格式为以下格式时，数据中存在问题：

{"key":number,"key":number}

这应仅限于：

{number,number}

问题：在按日期对事件进行排序后，如何删除数组键？

我可能会按照以下方式进行操作：

$headings = $result[0]['data'];
for ($i = 0; $i < count($result[1]); $i ++) {
    $data = $result[1][$i]['data'];
    $newdata = array();
    foreach($headings as $key)
        $newdata[] = isset($data[$key]) ? $data[$key] : 0;
    $result[1][$i]['data'] = $newdata;
}

$headers=$result[0]['data']；
对于（$i=0；$i

是否要删除所有键？希望

array\u values（）

能帮助您！我以前尝试过数组_值。array_values函数只删除所有键，而不是我要删除的键：D日期键保留。。。知道为什么会这样吗？
