FPDF顯示數據庫中的值的新手問題

Question

我是FPDF的新手，我才剛剛開始學習，

我正在嘗試使用PHP從數據庫顯示查詢

這是我的代碼。

<?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 } ?>

我得到了這個問題，FPDF錯誤：已經輸出了一些數據，無法發送PDF文件，我該如何解決？ 我想顯示數據庫中的值，一個解釋會很好。 :)

Answer 1

試試這一行：

$ PDF->細胞（0,10，$行[ 'CHENES']，0,0， “C”）;

Answer 2

嘗試這個：

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();
