我的原始数组是：

我正在尝试创建一个函数，该函数返回一个新数组，该数组可以在图表中使用，我创建的函数代码如下：

function chartData($results) {
$data = array();
$bots = 1;
$human = 1;
foreach($results as $subresults) {
    if($subresults['tracking_isbot'] === 1) {
        $data['bots'][$subresults['tracking_date']] = $bots++;
    } else {
        $data['human'][$subresults['tracking_date']] = $human++;
    }
}
return $data;
}

我从上述函数返回的数据不正确：

Array
(
[human] => Array
    (
        [2015-08-29] => 9
        [2015-08-30] => 27
        [2015-08-31] => 53
    )

[bots] => Array
    (
        [2015-08-29] => 6
        [2015-08-30] => 12
        [2015-08-31] => 26
    )

)

你能告诉我我在这里做错了什么......

2 个解决方案

好的，我想您的计数不正确，这对我来说绝对有意义，因为您正在总结所有内容并将其放入数组中...

我试着解释一下：每次被击中时，你都会增加 $bots 和 $human 的价值，并将其推入价值中。 这总结得非常快，并导致此时的计数 - 而不是该日期的数据计数。

尝试这个：

function chartData($results) {
    $data = array();

    foreach($results as $subresults) {
        $date = $subresults['tracking_date'];
        $key = 'human';

        if($subresults['tracking_isbot'] === 1) {
            $key = 'bots';
        } 

        if(!array_key_exists($date, $data[$key]))
            $data[$key][$date] = 1;
        else
            $data[$key][$date]++;
    }
    return $data;
}

希望这可以帮助

function chartData($results) {

    $newArray = array('human' => array(), 'bots' => array());

    foreach($results as $index => $result) {
        if($result['tracking_isbot'] == 1) {
            if(isset($newArray['bots'][$result['tracking_date']])) {
                $newArray['bots'][$result['tracking_date']] += 1;
            } else {
                $newArray['bots'][$result['tracking_date']] = 1;
            }
        } else {
            if(isset($newArray['human'][$result['tracking_date']])) {
                $newArray['human'][$result['tracking_date']] += 1;
            } else {
                $newArray['human'][$result['tracking_date']] = 1;
            }
        }
    }

    return $newArray;
}

您正在尝试计算每个tracking_date的人员/机器人数量，如果我是正确的，那么上述函数将完成此操作。
