我有一个这样的数组

Array
(
    [interswitch] => Array
        (
            [0] => Array
                (
                    [month] => 8
                    [transactions] => 5
                )

            [1] => Array
                (
                    [month] => 9
                    [transactions] => 1
                )

        )

    [visa] => Array
        (
            [0] => Array
                (
                    [month] => 8
                    [transactions] => 9
                )

        )

)

该数组由 SQL 查询生成，该查询查询一个表并计算每个月的记录。其中 [month] 表示日历月份。我想将此数据与接受此格式数据的 HighCharts 一起使用

{name: 'Tokyo',data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1,95.6, 54.4]}

如何将我的数组转换为更具可读性的数组，然后可以由 JSON 编码并转换为上述格式我已经尝试过

$_monthly_gateway_usage = array(
                array(
                    "name"=>"Interswitch",
                    "data"=>$this->parse_monthly_usage_data($monthly_gateway_usage['interswitch'])
                ),
                array(
                    "name"=>"Visa",
                    "data"=>$this->parse_monthly_usage_data($monthly_gateway_usage['visa'])
                )

            );

private function parse_monthly_usage_data($usage_data = array()) {

            $months = array("1","2","3","4","5","6","7","8","9","10","11","12");
            $_d = array();
            foreach ($months as $month) {
                foreach ($usage_data as $key => $d) {
                    if($d['month'] == $month)
                    {
                        $_d[] = $d['transactions'];
                    }
                    else
                    {
                        $_d[] = 0;
                    }
                }
            }

            return $_d;
        }

任何帮助将不胜感激

这是一个较短的形式：循环索引基于月份

$_d = array();
for($i=1;$i<=12;$i++){
    foreach($usage_data as $v){
        $_d[$i] += ($v['month']==$i) ? $v['transactions'] : 0;
    }
}
