Question

我正在尝试创建一个wordpress插件，我需要从数据库中导出一些东西。

    <?php
ob_start();
global $wpdb;
$statements = $wpdb->get_results( "SELECT * FROM wp_paypal_statements ORDER BY id DESC" );

if (isset($_POST["export"])) 
{
    ob_end_clean();

    $csv = "User ID, PayPal Email, Amount \n";//Column headers
        foreach ($statements as $record)
        {
            $csv .= $record->id . ',' . $record->paypal_email. ',' . $record->amount . "\n"; //Append data to csv
        }
        $csv_handler = fopen("php://output", 'w');
        fwrite ($csv_handler,$csv);
        fclose ($csv_handler);

    header('Content-Type: text/csv; charset=utf-8');
    header('Content-Disposition: attachment; filename=data.csv');

    exit();
}

我正在获取该文件的html源代码。例如：

这就是我的代码看起来如何，我没有看到这里有什么问题。有帮助吗？谢谢！
