php - 在图形的 fpdf 数据中插入数组

Question

我必须在图形数据中放置一个数组 这是原始格式

$data = array( "DATA_1title" => DATA1, "DATA_2title" => DATA2);

这是 php 语句

    $sqlb = "SELECT date_format(datesales, '%M %D %Y') as datesales,
    sum(amount) as amount from sales
    where date(datesales) <= curdate() and
    date(datesales) >= curdate() - interval 6 day
    group by DATE_FORMAT(datesales, '%M %D %Y')";
    $resultb = $conn->query($sqlb);
    while($rowb = $resultb->fetch_assoc())
    {
        $datesales = $rowb['datesales'];
        $amount = $rowb['amount'];
    }

我试过这段代码

    $sqlb = "SELECT date_format(datesales, '%M %D %Y') as datesales,
    sum(amount) as amount from sales
    where date(datesales) <= curdate() and
    date(datesales) >= curdate() - interval 6 day
    group by DATE_FORMAT(datesales, '%M %D %Y')";
    $resultb = $conn->query($sqlb);
    while($rowb = $resultb->fetch_assoc())
    {
        $datesales=$rowb['datesales'];
        $amount=$rowb['amount'];

        $data = array( "$datesales" => $amount,);
    }

但它只显示一个值 而不是一组值 这个我也试过

$sqlb = "SELECT date_format(datesales, '%M %D %Y') as datesales,
    sum(amount) as amount from sales
    where date(datesales) <= curdate() and
    date(datesales) >= curdate() - interval 6 day
    group by DATE_FORMAT(datesales, '%M %D %Y')";
    $resultb = $conn->query($sqlb);
    while($rowb = $resultb->fetch_assoc())
    {
        $data = array( "$rowb['datesales']" => $rowb['amount'],);
    }

但我得到了相同的结果 我想要的是，不是每次都手动输入键和值，而是可以使用我所做的 sql 语句将其从数据库中拉出。

Instead of this 
$data = array( "DATA_1title" => DATA1, "DATA_2title" => DATA2);

I want it to be like this
**SQL STATEMENT HERE**
$data = array( "$datetimes" => $amount);

$datetimes refers to the alias in the sql statement which is an array
so is $amount

您可以简单地使用一个值作为键，另一个作为值。例如:

// instead of your while loop
foreach($resultb as $rowb) {
    $data[$rowb['datesales']] = $rowb['amount'];
}
