Question

I am using a foreach statement to echo the data I have out to a jquery chart (flotchart). The form needs to be {"label", data}, {"label", data}, {"label", data}

But my foreach statement adds a comma after every row including the last row which I can’t have a comma because it is breaking the script.

I am currently using

foreach ($bycountry as $country) {print 
'{ label: "' . $country['origincountry'] . '", data: ' . $country['countrytotal']. ' }, ';
}

This gives me: {"label", data}, {"label", data}, {"label", data},

I need no comma on the last row

Answer 1

Have you tried just json_encode it?

$country_to_json = array(
    array('label'=>'Portugal', 'data'=>12), 
    array('label'=>'india', 'data'=>13) 
);

echo json_encode($country_to_json);

You’ll need to reorganize your array a bit, but it is a much cleaner approach.

Another way is to use implode, however you’ll need to reorganize your array anyway:

$country_for_implode = array();
foreach($bycountry as $country){
   $country_for_implode[] = "{ label: {$country['origincountry']}, data: {$country['countrytotal']}}";
}

echo implode(",", $country_for_implode);
