Question

当我将鼠标悬停在栏上时，我可以弹出日期，但我想分析日期范围内的数据。我看了无数的例子。我搞砸了更改索引并为其创建了一个变量。如果我在数据库中已经有一个datetime变量，那么提交时该如何实现？

<?php

$connect = mysqli_connect("localhost", "root", "password", "administrator_logins");
$query = 'SELECT sum(coins) as CausewayBay, now() AS date FROM cwb_coins';
$result = mysqli_query($connect, $query);
$rows = array();
$table = array();

$table['cols'] = array(
 array(
  'label' => 'date', 
  'type' => 'datetime'
 ),
 array(
  'label' => 'CausewayBay', 
  'type' => 'number'
 )
);

while($row=mysqli_fetch_array($result,MYSQLI_ASSOC)) 
{ 
    echo $row["date"]; 
$sub_array = array(); 
$sub_array[] = array( 
"v" => 'Date(' . $row["date"][0] . ')' 
);  
 $sub_array[] =  array(
      "v" => $row["CausewayBay"]*6
     );
 $rows[] =  array(
     "c" => $sub_array
    );
}
$table['rows'] = $rows;
$jsonTable = json_encode($table);

?>
