Question

我在条形图（Morris.bar）中无法获取数据（来自mysql）。我在数组中得到了我想要的结果，如下所示：

Array
(
[0] => Array
    (
        [total] => 200.00
        [year] => 2015
        [month] => 2
    )

[1] => Array
    (
        [total] => 500.00
        [year] => 2015
        [month] => 3
    )

[2] => Array
    (
        [total] => 500.00
        [year] => 2016
        [month] => 2
    )
[3] => Array
    (
        [total] => 600.00
        [year] => 2016
        [month] => 3
    )
[4] => Array
    (
        [total] => 600.00
        [year] => 2016
        [month] => 4
    )

)

我想在这样的条形图中获取数据（始终显示所有月份，如果没有值或空值，则回显0（零））

{month: "<?php echo $months[0]; ?>", <?php echo $last_year; ?>:VALUE_THAT_BELONGS_TO_JAN_2015(LAST_YEAR), <?php echo $this_year; ?>: VALUE_THAT_BELONGS_TO_JAN_2016 (CURRENT YEAR)},

现在完成脚本：

<?php $months = array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec"); ?>
 Morris.Bar({
element: 'graph_invoices_month',
data : [
{month: "<?php echo $months[0]; ?>", <?php echo $last_year; ?>: 1000, <?php echo $this_year; ?>: 1100},
{month: "<?php echo $months[1]; ?>", <?php echo $last_year; ?>: 3351, <?php echo $this_year; ?>: 629},
{month: "<?php echo $months[2]; ?>", <?php echo $last_year; ?>: 3269, <?php echo $this_year; ?>: 618},
{month: "<?php echo $months[3]; ?>", <?php echo $last_year; ?>: 3246, <?php echo $this_year; ?>: 661},
{month: "<?php echo $months[4]; ?>", <?php echo $last_year; ?>: 3257, <?php echo $this_year; ?>: 667},
{month: "<?php echo $months[5]; ?>", <?php echo $last_year; ?>: 3248, <?php echo $this_year; ?>: 627},
{month: "<?php echo $months[6]; ?>", <?php echo $last_year; ?>: 3171, <?php echo $this_year; ?>: 660},
{month: "<?php echo $months[7]; ?>", <?php echo $last_year; ?>: 3171, <?php echo $this_year; ?>: 676},
{month: "<?php echo $months[8]; ?>", <?php echo $last_year; ?>: 3201, <?php echo $this_year; ?>: 656},
{month: "<?php echo $months[9]; ?>", <?php echo $last_year; ?>: 3215, <?php echo $this_year; ?>: 622},
{month: "<?php echo $months[10]; ?>", <?php echo $last_year; ?>: 3215, <?php echo $this_year; ?>: 622},
{month: "<?php echo $months[11]; ?>", <?php echo $last_year; ?>: 3215, <?php echo $this_year; ?>: 622}

],

xkey: 'month',
ykeys: ['<?php echo $last_year; ?>', '<?php echo $this_year; ?>'],
labels: ['<?php echo $last_year; ?>', '<?php echo $this_year; ?>'],
resize: true,
barColors: ['<?php echo $this_year_color; ?>', '<?php echo $last_year_color; ?>'],
xLabelAngle: 60
});

进一步澄清：这就是我之后：

month: Jan 2015 = 0 : Jan 2016 = 0
month: Feb 2015 = 200 : Feb 2016 = 500
month: Mar 2015 = 500 : Mar 2016 = 600
month: Apr 2015 = 0 : Apr 2016 = 600
month: May 2015 = 0 : May 2016 = 0
month: Jun 2015 = 0 : Jun 2016 = 0
month: Jul 2015 = 0 : Jul 2016 = 0
month: Aug 2015 = 0 : Aug 2016 = 0
month: Sep 2015 = 0 : Sep 2016 = 0
month: Oct 2015 = 0 : Oct 2016 = 0
month: Nov 2015 = 0 : Nov 2016 = 0
month: Dec 2015 = 0 : Dec 2016 = 0

希望有人可以对此有所了解，因为它让我疯了！在此先感谢您的帮助！

Phewww，我设法回答了我自己的问题。如果其他人需要类似的解决方案，那么这就是我的代码：

    <?php $months = array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec"); ?>
    Morris.Bar({
    element: 'graph_invoices_month',
    data : [
      <?php foreach($months as $month => $value){ ?>
        {month: "<?php echo $value; ?>", 
      <?php echo $last_year; ?>: 

      <?php $total_revenue_last_year = 0; ?>
      <?php foreach($total_revenue_by_months as $total_revenue_by_month){ ?>
      <?php if (($month + 1) == $total_revenue_by_month['month'] && $last_year == $total_revenue_by_month['year']) { ?>
      <?php $total_revenue_last_year =  $total_revenue_by_month['total_month_revenue']; ?> 
      <?php } ?>
      <?php } ?>
      <?php if (isset($total_revenue_last_year)){
        echo $total_revenue_last_year . ",";
        } else { echo "0,"; } ?>


      <?php echo $this_year; ?>: 
      <?php $total_revenue_this_year = 0; ?>
      <?php foreach($total_revenue_by_months as $total_revenue_by_month){ ?>
      <?php if (($month + 1) == $total_revenue_by_month['month'] && $this_year == $total_revenue_by_month['year']) { ?>
      <?php $total_revenue_this_year =  $total_revenue_by_month['total_month_revenue']; ?> 
      <?php } ?>
      <?php } ?>
      <?php if (isset($total_revenue_this_year)){
        echo $total_revenue_this_year . "},";
        } else { echo "0},"; } ?>

      <?php }  ?>          
    ],

    xkey: 'month',
    ykeys: ['<?php echo $last_year; ?>', '<?php echo $this_year; ?>'],
    labels: ['<?php echo $last_year; ?>', '<?php echo $this_year; ?>'],
    resize: true,
    barColors: ['<?php echo $this_year_color; ?>', '<?php echo $last_year_color; ?>'],
    xLabelAngle: 60
});

如何循环和操作数组（Morris.bar）
