用于highcharts热图的php绘图系列

以上是我的php mysql响应

对于highchart，热图月份在x轴上绘制，状态在y轴上绘制

我有一个问题，如何映射热图系列的值。 参见热图系列绘图，如[[0,0,10]，[0,1,29]]等。。。。 请参阅下面的链接

我必须使用php绘制序列。

尝试以下示例代码：

Array
(
    [0] => Array
        (
            [month] => oct
            [value] => 10
            [state] => MU
        )

    [1] => Array
        (
            [month] => nov
            [value] => 29
            [state] => MU
        )

    [2] => Array
        (
            [month] => oct
            [value] => 88
            [state] => DL
        )

    [3] => Array
        (
            [month] => nov
            [value] => 67
            [state] => DL
        )

    )

<?php
$states = ['DL','BL','MU','OU'];
$data_array = [['month' => 'oct', 'value' => 10, 'state' => 'MU'],['month' => 'jan', 'value' => 12, 'state' => 'OU']];

$graph_array = [];
foreach ($data_array as $data){
    $state = array_search($data['state'], $states);
    $month = date('n',strtotime($data['month']));
    $graph_array[] = [$state,$month,$data['value']];
}

print_r($graph_array);
