我正在尝试编写一个函数，它将我的数组转换为json数据，用于Morris Area图表从数据库中提取的原始数组如下：

最终的json输出应如下所示：
{ date: '2015-08-29', human: 9, bots: 6 },
{ date: '2015-08-30', human: 18, bots: 6 },
{ date: '2015-08-31', human: 26, bots: 14 }
从原始数组：
[date] => xxxx-xx-xx as date:'xxxx-xx-xx'
[isbot] => 0 should be counted as hits from human and
[isbot] => 1 should be counted as hits from bots.
我已创建此功能但无法以所需格式返回数据：
function chartData($results) {
$data = array();
foreach($results as $index => $result) {
if($result['tracking_isbot'] == 1) {
if(isset($data[$result['tracking_date']]['bots'])) {
$data[$result['tracking_date']]['bots'] += 1;
} else {
$data[$result['tracking_date']]['bots'] = 1;
}
} else {
if(isset($data[$result['tracking_date']]['human'])) {
$data[$result['tracking_date']]['human'] += 1;
} else {
$data[$result['tracking_date']]['human'] = 1;
}
}
}
return $data;
}
上面的函数在json encode：
之前返回数组Array
(
[2015-08-29] => Array
(
[human] => 9
[bots] => 6
)
[2015-08-30] => Array
(
[human] => 18
[bots] => 6
)
[2015-08-31] => Array
(
[human] => 26
[bots] => 14
)
)
上面数组的json_encode（）：
{"2015-08-29":{"human":9,"bots":6},"2015-08-30":{"human":18,"bots":6},"2015-08-31":{"human":26,"bots":14}}
答案 0 :(得分：0)
您还需要保存日期：
function chartData($results) {
$data = array();
foreach($results as $result) {
$t_date = $result['tracking_date'];
if(!isset($data[$t_date])) {
$data[$t_date] = array(
'date' => $t_date,
'human' => 0,
'bots' => 0,
);
}
$data[$t_date]['bots'] += $result['tracking_isbot'];
$data[$t_date]['human'] += (1 - $result['tracking_isbot']);
}
return $data;
}

感谢@Matteo Tassinari，感谢您的解决方案。我稍微修改了你的代码，现在它完全适合我...
function chartData($results) {
$data = array();
$newArray = array();
foreach($results as $result) {
$t_date = $result['tracking_date'];
if(!isset($data[$t_date])) {
$data[$t_date] = array(
'date' => $t_date,
'human' => 0,
'bots' => 0,
);
}
$data[$t_date]['bots'] += $result['tracking_isbot'];
$data[$t_date]['human'] += (1 - $result['tracking_isbot']);
}
foreach($data as $key => $value) {
array_push($newArray, $value);
}
return $newArray;
}
