Question

I am using http://www.jqplot.com/tests/pie-donut-charts.php which needs to have data given to it in the following format:

//JavaScript
var data = [
  ['Heavy Industry', 12],['Retail', 9], ['Light Industry', 14],
  ['Out of home', 16],['Commuting', 7], ['Orientation', 9]
];

The data is generated serverside with PHP. I am manually creating the string as follows:

//PHP
$string.='["'.$row['name'].'",'.$row['count'].'],';

I would rather just create an array, and use json_encode() or something similar to create the data. Any suggestions how I would do so?

Answer 1

$array = array(
    array(
        "Heavy Industry",
        12
    ),
    array(
        "Retail",
        9
    )
);
$json = json_encode($array);
var_dump($json); // "[["Heavy Industry",12],["Retail",9]]"
