Saya dapati banyak data dari pangkalan data, satu demi satu, tatasusunan dua dimensi, formatnya adalah seperti berikut:
Array
(
[0] => Array
(
[id] => 29
[user_id] => 1
[car_no] => 234567
)
[1] => Array
(
[id] => 21
[user_id] => 1
[car_no] => 23565
)
[2] => Array
(
[id] => 23
[user_id] => 1
[car_no] => 12345
)
[3] => Array
(
[id] => 28
[user_id] => 1
[car_no] => 124455
)
[4] => Array
(
[id] => 6
[user_id] => 1
[car_no] => 12345
)
[5] => Array
(
[id] => 7
[user_id] => 2
[car_no] => 22
)
[6] => Array
(
[id] => 3
[user_id] => 2
[car_no] => 粤T863
)
[7] => Array
(
[id] => 25
[user_id] => 3
[car_no] => 12345
)
);
Apakah yang perlu saya lakukan untuk mengklasifikasikan pengguna dengan user_id yang sama? Formatnya adalah seperti berikut:
Array
(
[0] => Array
(
[user_id] => 8
[login] => 18620982882
[car_no] => Array
(
[0] => 粤A123
)
)
[1] => Array
(
[user_id] => 7
[login] =>
[car_no] => Array
(
[0] => 粤T456
[1] => 123456
)
)
[2] => Array
(
[user_id] => 2
[login] => 13318029123
[car_no] => Array
(
[0] => 粤T863
[1] => 22
)
)
[3] => Array
(
[user_id] => 1
[login] => 15088138542
[car_no] => Array
(
[0] => 12345
[1] => 23565
[2] => 12345
[3] => 124455
[4] => 234567
)
)
)
Pendekatan saya adalah seperti berikut, dan ia mencapai matlamat, tetapi rasanya terlalu tidak cekap:
//先把id去重组成一个数组,计算需要处理的$data的子数组个数,然后遍历,如果user_id与去重后的那个数组的键值相同,就把这个值存到新数组里面去,组成一个新的二维数组。
private function group_sort($unique, $num, $data) {
foreach ($unique as $key => $value) {
for ($i = 0; $i < $num; $i++) {
if ($data[$i]['user_id'] == $value) {
$data_format[$key]['user_id'] = $data[$i]['user_id'];
$data_format[$key]['login'] = $data[$i]['login'];
$data_format[$key]['car_no'][] = $data[$i]['car_no'];
}
}
}
return $data_format;
}
Adakah cara untuk menyemaknya terus daripada pangkalan data? Selain itu, log masuk di sini perlu ditanya dari jadual pengguna Dalam jadual kenderaan, hanya user_id dikaitkan dengan jadual pengguna. Ia perlu dinomborkan selepas membuatnya. Saya merancang untuk menggunakan array_chunk untuk memisahkan tatasusunan. Tolong beri saya nasihat daripada pakar.
Kod lengkap adalah seperti berikut:
/**

* @desc 后台查询用户信息,可以根据登录名,手机号,邮箱号,车牌号等查询,不传查询参数表示获取全部用户信息
* @param search string N N 需要搜索的条件,可以是登录名,手机号,邮箱号,车牌号,例如:123,不传参数表示获取全部
