Question

我需要将这些行和输出水平输出，并将Dates作为列标题。我已经看过其他解决方案，但我是一个新手，无法弄明白。

     ENV      | SUM_TRX | TRX_DATE

    mfg_Dev   | 392     |  2018-05-01

考虑这个粗略的例子......

<?php

//include('path/to/connection/statme.nts');

$query = "
SELECT env
     , sum_trx
     , trx_date
  FROM my_table
 ORDER
    BY env,trx_date;
";

$result = mysqli_query($conn,$query);

$array = array();

while($row = mysqli_fetch_assoc($result)){
$array[] = $row;
}

foreach($array as $v){
$new_array[$v['env']][$v['trx_date']] = $v['sum_trx'];
}


print_r($new_array);
?>

...输出

Array

    [Dev] => Array
        (
            [2018-05-01] => 392
