如何在php中将php数据添加到highchart js文件中

my code:

series: [{
            name: 'Brands',
            colorByPoint: true,
            <?php
            $models="SELECT * FROM purchase_info GROUP BY model_name";
            $models_querry=mysql_query($models);
            while($models_data=mysql_fetch_assoc($models_querry))
            {
            $model_name[]=$models_data['model_name'];
            }
            ?>
            data: [{
                name: ['<?php echo join($model_name, ',') ?>'],
                y: 56.33,
                drilldown: 'Hero Honda'
            }]
        }],

In my project i'm using high charts, in that how can i add php data into that, i just collect all data and saved into one variable named as $model_name[], after that i pass the array value into data, but in that it will not spitted, all data's are echoed into single one.

Use ajax for that..see the script code

$.ajax({
                    type: "POST",
                    url: 'ajax.php',             
                    success: function(data) {
                        a = jQuery.parseJSON(data); 
                        i=0;
                        $.each( a.total_potential_score, function( key, val ) {
                           data1[i] = parseFloat(val);
                            i++;
                        });
                        rasterize_function(data1);
                      }
                });

Ajax file look like this

$a[0] = "1";
$a[1] = "2";
$a1['total_potential_score'][0] = "1";
$a1['department_name'][0] = "aaaaa";
$a1['total_potential_score'][1] = "3";
$a1['department_name'][1] = "bbbbb";
echo json_encode($a1);

function for the highchart displayed here

function rasterize_function(data1)  {
       var seriesArray = [];
       $.each( data1, function( key, val ) {
            seriesArray.push({
            name: "aaaa",
            data: [val],
            animation: false,
            dataLabels: {
                enabled: true,

                    fontSize: '13px',
                    fontFamily: 'Verdana, sans-serif'
                }
            }

        });
    });
       $('#container').highcharts({
