强制下载csv [复制]

I want to create a function for force download CSV file but the CSV file displays its content like print_r() I know this is not the right way but otherwise it doesn't display it at all.

function export_to_csv($result) {

    $shtml = print_r($result);

    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="data.csv"');

    echo $shtml;
}

This is how I created the CSV file through XML

function createCsv($xml, $f) {

    foreach ($xml->children() as $item) {

        $hasChild = (count($item->children()) > 0) ? true : false;

        if (!$hasChild) {
            if (!empty($item)) {
                $put_arr = array($item->getName(), $item);
                fputcsv($f, $put_arr, chr(9));
            }
        } else {
            createCsv($item, $f);
        }
    }
}

Any ideas?

You need to return print_r results with adding true as a second argument:

$shtml = print_r($result, true);
