can't use php array in javascript

[subhomoy]

Hello everyone

I have an array ( php ) which i want it to use in javascrip. i have used json encode function but this is not the problem. I want to use the values from an array and plot a graph

 

The PHP array looks like this

        <?php                 
$visits = array(           
            'UK' => 5,
            'US' => 10,
            'AS' => 15,
            'AD' => 20,
            'FG' => 25,
            'HF' => 30,
            'DG' => 35,
            'JH' => 40,
            'ET' => 45,
            'HG' => 50,
            'KT' => 55,
            'ER' => 10,
            'UI' => 65,
            'ER' => 70,
            'UY' => 75,
            'UT' => 80,
            'UK' => 5  
        );
        ?>

and the javascript file is

<script type="text/javascript">
         var arr  = "<?php  json_encode($visits) ?>";
$(function () {
        $('#container').highcharts({
            chart: {
                type: 'area'
            },
            title: {
                text: 'Total Impressions'
            },
            subtitle: {
                text: ''
            },
            xAxis: {
                labels: {
                    formatter: function() {
                        return this.value; // clean, unformatted number for year
                    }
                }
            },
            yAxis: {
                title: {
                    text: 'Hits'
                },
                labels: {
                    formatter: function() {
                        return this.value / 1000 +'k';
                    }
                }
            },
            tooltip: {
                pointFormat: '{series.name} produced <b>{point.y:,.0f}</b><br/>warheads in {point.x}'
            },
            plotOptions: {

Any help will be greatly appreciated...

 

Thank in advance,....

json_encode() doesn't output anything. you would need to echo the output in order to send it to the browser.

ok noted the above mistake but how to loop through the values???

Your PHP array will be a JavaScript object, so you can use a for (property in object) loop

e.g.

for (p in arr) {
if (arr.hasOwnProperty(p)) {
// do something
}
}

Also, you have to remove the quotes from the "<?php json_encode($visits) ?>"; Edited March 31, 2014 by nogray
