你能告诉我我做错了什么吗…好吧，我想你的计数是不正确的，这对我来说绝对有意义，因为你把所有的东西都加起来放到数组中 我试图解释： 您正在增加$bots和$human的价值，每次它们被击中时，都会将其推到价值中。这会很快总结出来，并导致在这一点上的一个计数-而不是这个日期的数据计数 试试这个：
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 $data;
}
function chartData($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跟踪日期的人类/机器人的数量，如果我是正确的，那么上面的函数将完成此操作。您可以先告诉我们您的阵列应该是什么样子。您是否可以发布您的预期输出
我得到的数据。。。不正确的
