FPDF显示数据库中的值的新手问题

Question

我是FPDF的新手，我才刚刚开始学习。

我正在尝试使用PHP显示来自数据库的查询

这是我的代码。

<?php
    session_start();
    $conn = @mysql_connect("","","");
    $db = @mysql_select_db("");
    require("../pdf/fpdf.php");

$qry = "SELECT sum(order_detail.quantity*order_detail.price) as chenes, orders.date
        FROM order_detail 
        LEFT JOIN orders 
        ON order_detail.orderid=orders.serial";

mysql_set_charset("UTF8");
$result = @mysql_query($qry);
if($result === FALSE) {
    die(mysql_error()); // TODO: better error handling
}   
while ($row=mysql_fetch_array($result)){    
?>
<?php
$pdf=new FPDF();

$pdf->AddPage();

$pdf->SetFont("Arial","","13");
$pdf->Cell(0,10,"Sales Reports",0,1,"C");

$pdf->SetFont("Arial","I","10");
$pdf->Cell(0,10,"$row[chenes]",0,0,"C");
$pdf->Output();
?>

<?php } ?>

我得到了这个问题，FPDF错误:一些数据已经输出，无法发送PDF文件，我如何解决它？我想要显示来自数据库的值，一个解释会很好。:)

Answer 1

试试下面这行：

$pdf->Cell(0,10，$row‘’chenes‘，0，0，"C")；

Answer 2

试试这个：

define('FPDF_FONTPATH', '../pdf/font/');
require("../pdf/fpdf.php");

$pdf=new FPDF();
$pdf->Open();
$pdf->AddPage();
$pdf->SetFont("Arial","","13");

$pdf->Cell(0,10,"Sales Reports",0,1,"C");

$pdf->SetFont("Arial","I","10");
while ($row=mysql_fetch_array($result)){    
    $pdf->Cell(0,10,$row["chenes"],0,0,"C");
}
$pdf->Output();
