javascript - echo php variable in Highcharts -

-

how echo php variable script of highchart js? im using column chart

<?php $value=75 ?>

at series section 

series: [{             name: 'traf',             data: [<?php echo $value?>, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]          }]

any solution helps.

mixing php js bad habit, can either store $value in hidden field:

<input type="hidden" value="<?=$value?>" id="txtchart" name="txtchart" />

then in javascript:

var txtchart = $("#txtchart").val(); series: [{         name: 'traf',         data: [txtchart, 71.5, 106.4....]     }]
