PHP
1

I need to get the sum total of a sub-child element from mxl file My structure of xml file is as follow

<pagevalues>
    <ac>
        <b1>1</b1>
        <b2>2</b2>
        <b3>3</b3>
        <b4>4</b4>
        <b5>5</b5>
        <pc>6</pc>
    </ac>
<pagevalues>

I tried following approach but get Total =0

$xml = simplexml_load_file($target_url);
$total=0;
foreach($xml->ac as $data)
{    
    $total += $data;
}
echo 'Total is: ' . $total;
