Question

我使用脚本将mysql数据库导出到.csv文件，但它也包含导出文件下面页面的所有html。

$fields = array();
    $csv = array();
    /*** mysql hostname ***/
    $hostname = DB_HOST;
    $dbname = DB_NAME;
    /*** mysql username ***/
    $username = DB_USER;
    /*** mysql password ***/
    $password = DB_PASS;
    try {
        $dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);
        $tablename = 'comments';
        $sql = 'SHOW COLUMNS FROM `'.$tablename.'`';

        $stmt = $dbh->query($sql);
        $stmt->execute();
        while($row = $stmt->fetch(PDO::FETCH_ASSOC))
        {
            array_push($fields, $row['Field']);
        }

        array_push($csv, $fields);
        $sql = 'SELECT `name`,`comment`,`email` FROM `'.$tablename.'`';

        $stmt = $dbh->query($sql);
        $stmt->execute();

        $csv = array();

        while($row = $stmt->fetch(PDO::FETCH_NUM))
        {
            array_push($csv, $row);
        }

        $fp = fopen('file.csv', 'w');

        foreach ($csv as $row) {
            fputcsv($fp, $row);
        }

        fclose($fp);
        header("Content-type: application/csv");
        header("Content-Disposition: attachment; filename=comments.csv");
        header("Pragma: no-cache");
        header("Expires: 0");
        readfile('file.csv');
        $dbh = null;
    } catch(PDOException $e) {
        echo $e->getMessage();
    }

如果有人知道如何纠正这一点，我们将不胜感激。感谢

Answer 1

似乎

exit;

脚本停止将任何HTML输入.csv

后

导出到CSV会将所有HTML放在文件的底部
