FPDF錯誤：一些數據已經輸出 - PHP腳本

嗨，大家好我想修改一個PDF文件並將它存儲在我的服務器，但我不斷收到此錯誤：FPDF error: Some data has already been output, can't send PDF file，我無法設法它的原因。FPDF錯誤：一些數據已經輸出 - PHP腳本

有人知道這是否是從哪裏來的？

我們可以看到完整的PHP腳本。這個問題似乎是最後的$ pdf-> output（）調用。由於某些內容已經發送，FPDF無法將輸出發送到瀏覽器。在打開<？php標記之前，它可以像空白行一樣簡單。 – SheppardDigital

其實我的腳本長300多行，我還應該發佈嗎？在<？php標記之前沒有空行，最後也沒有空行 – DeveloppeurDuTurfu

查看可能會輸出數據的任何內容，echo命令，<？php標記之前的空行。 – SheppardDigital

有過再看看你的腳本，它看起來像你可能會創建多個PDF文件，但只能輸出最後一個。

我認爲includes和FPDF實例化應該在foreach之外，像這樣;

require_once('../fpdf17/fpdf.php'); 
require_once('../FPDI/fpdi.php'); 

$pdf = new FPDI(); 

foreach($destinataireFR as $destinataireFR) { 
    $mail->Body = "<p style='font-family:Calibri'>Bonjour,<br/><br/><a href='$destinataireFR[lien]' style='font-size:1.1em'>Cliquez ici</a> pour ouvrir le fichier <b>$rapportFR</b>.<br/><br/>Cordialement,<br/><br/><b style='color:#4271BE'>L'Equipe Horizon Soft Commodities</b><br/>01.49.89.46.16<br/><a href='mailto:[email protected]'>[email protected]</a><br/><br/><br/><p style='font-size:0.8em'>Si vous souhaitez vous d&eacute;sinscrire et ne plus recevoir ces messages, <a href='mailto:[email protected] &subject=Desinscription'>cliquez ici</a>.</p><br/>$messageAdditionel</p>"; 
    $mail->Subject = "$rapportFR"; 
    $mail->AddAddress("$destinataireFR[mail]"); 
    if($categ == 27) 
    { 
     // add a page 
     $pdf->AddPage(); 
     // set the source file 
     $pdf->setSourceFile($dirFR . "/" . $pdfFR); 
     // import page 1 
     $tplIdx = $pdf->importPage(1); 
     // use the imported page and place it at point 0,0 with a width of 300 mm(pour un centrage comme reel) 
     $pdf->useTemplate($tplIdx, 0, 0, 300); 
     $pdf->SetXY(70, 70); 
     $pdf->Write(0, "test"); 
     $pdf->SetXY(100, 80); 
     $pdf->Write(0, "test"); 
    } 
if ($mail->Send()){ 
    // echo "success<br/>"; 
}else{ 
    // echo "fail : ". $mail->ErrorInfo . "<br/>"; 
} 
$mail->ClearAddresses(); 
} 
$pdf->Output();

哦你是對的，它不應該在foreach！只是移動它，但問題仍然存在.. – DeveloppeurDuTurfu

可悲的是，沒有看到所有的代碼，很難分辨出問題是什麼，它當然不會與你已粘貼的代碼 – SheppardDigital

是的，我明白了，那麼這裏是完整的腳本，對不起，如果它有點長：p – DeveloppeurDuTurfu

打開和關閉php標籤後立即添加這些功能。

<?php 
ob_start(); 
// php code here 
ob_end_flush(); 
?>

嗨，感謝您的回覆，但它似乎並沒有在這裏工作:( – DeveloppeurDuTurfu

你在哪裏添加ob_start（）;？我可以在你的代碼中看到它嗎？ –

確定我剛剛添加了腳本的開始！ – DeveloppeurDuTurfu
