我的期末课程有一个测试。我做了一些函数，但它停留在值数组之和上。
我从MySQL调用数据
$stmt = $conn->prepare("SELECT r.id,id_penyakit,nama_penyakit,id_puskesmas,nama_puskesmas,created_at FROM riwayat r WHERE id_puskesmas = :id_puskesmas");
$stmt->bindValue(':id_puskesmas', $page_cat);
$stmt->execute();
$stmt->setFetchMode(PDO::FETCH_ASSOC);
$chartriwayat = $stmt->fetchAll();
它将产生一个像这样的数组
Array
(
[0] => Array
(
[id] => 4
[id_penyakit] => 1
[nama_penyakit] => Ayan
[id_puskesmas] => 5
[nama_puskesmas] => Puskesmas Melur
[created_at] => 2024-02-01 10:32:14
)
[1] => Array
(
[id] => 5
[id_penyakit] => 2
[nama_penyakit] => kutilan
[id_puskesmas] => 5
[nama_puskesmas] => Puskesmas Melur
[created_at] => 2024-02-01 10:32:18
)
[2] => Array
(
[id] => 6
[id_penyakit] => 3
[nama_penyakit] => Panuan
[id_puskesmas] => 5
[nama_puskesmas] => Puskesmas Melur
[created_at] => 2024-02-01 10:32:22
)
[3] => Array
(
[id] => 8
[id_penyakit] => 3
[nama_penyakit] => Panuan
[id_puskesmas] => 5
[nama_puskesmas] => Puskesmas Melur
[created_at] => 2024-01-01 10:32:22
)
[4] => Array
(
[id] => 9
[id_penyakit] => 3
[nama_penyakit] => Panuan
[id_puskesmas] => 5
[nama_puskesmas] => Puskesmas Melur
[created_at] => 2024-01-01 11:32:22
)
)
然后我需要将数据放入新数组中，例如具有相同“id_penyakit”和同一日期月份的总和值
我已经尝试过这段代码并努力创建一个我想要的新数组
$arraychartriwayat1 = $arraychartriwayat2 = $arraychartriwayat = array();
$ArrayFuncmonth = array(
'January'=>0,
'February'=>0,
'March'=>0,
'April'=>0,
'Mei'=>0,
'June'=>0,
'July'=>0,
'August'=>0,
'September'=>0,
'October'=>0,
'November'=>0,
'December'=>0
);
foreach ($chartriwayat as $key => $value) {
$arraychartriwayat1[$value['id_penyakit']] = array(
"name" => $value['nama_penyakit'],
"data" => $ArrayFuncmonth,
);
}
foreach ($chartriwayat as $key => $value) {
$riwayatmonth = date('F', strtotime($value['created_at']));
foreach ($ArrayFuncmonth as $ke => $va) {
$month = $ke;
if($riwayatmonth==$month){
if(isset($ArrayFuncmonth[$ke])){
$ArrayFuncmonth[$ke]+=1;
}else{
$ArrayFuncmonth[$ke]+=0;
}
}
$arraychartriwayat[$value['id_penyakit']] = array(
"name" => $value['nama_penyakit'],
"data" => $ArrayFuncmonth,
);
}
}
这段代码的结果是这样的
Array
(
[1] => Array
(
[name] => Ayan
[data] => Array
(
[January] => 0
[February] => 1
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
[2] => Array
(
[name] => kutilan
[data] => Array
(
[January] => 0
[February] => 2
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
[3] => Array
(
[name] => Panuan
[data] => Array
(
[January] => 2
[February] => 3
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
)
但问题是数据总是相加，而不是每个“id_penyakit”都不同
代码应该增加与月份具有相同“id_penyakit”和相同“created_at”的值
我问的是这样的
Array
(
[1] => Array
(
[name] => Ayan
[data] => Array
(
[January] => 0
[February] => 1
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
[2] => Array
(
[name] => kutilan
[data] => Array
(
[January] => 0
[February] => 1
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
[3] => Array
(
[name] => Panuan
[data] => Array
(
[January] => 2
[February] => 1
[March] => 0
[April] => 0
[Mei] => 0
[June] => 0
[July] => 0
[August] => 0
[September] => 0
[October] => 0
[November] => 0
[December] => 0
)
)
)
“February”中的数据必须为 1，因为 $chartriwayat 中显示 ID“3”的 penyakit“Panuan”
请帮助我完成我的期末课程测试。
