Question

我正在尝试使用FPDF创建pdf文件。一切都在localy工作正常，但一旦我把所有东西都移到服务器上它就不再工作了。我收到以下错误消息： FPDF错误：某些数据已经输出，无法发送PDF文件（输出从/users/simplesystems/www/fpdf/pdf_rechnungen/Rechnungen.php:81开始）

这是上述路径中的代码

<?php
error_reporting(E_ALL);
include('rechnungenclass.php');
$rechnungen = new rechnungenclass();
$rechnungen->rechnungenausgeben();
$rechnungen->rechnungenhinzufuegen();
?>

我尝试删除所有的回声 - ＆gt;但仍然是同一个问题。在当地完美运作。

你能帮帮我吗？

**更新 - ＆gt; Rechnungen.php的代码
