我正在使用TCPDF生成PDF,我想將生成的PDF作爲blob保存在MySQL數據庫中。我應該將哪些數據保存到數據庫? 代碼的PDF頁面PHP MySQL:將PDF保存到數據庫
<?php
require_once('../config/lang/eng.php');
require_once('../tcpdf.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 001');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
// set default header data
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING);
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
//set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
//set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
//set some language-dependent strings
$pdf->setLanguageArray($l);
// ---------------------------------------------------------
// set default font subsetting mode
$pdf->setFontSubsetting(true);
// Set font
// dejavusans is a UTF-8 Unicode font, if you only need to
// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
$pdf->SetFont('dejavusans', '', 14, '', true);
// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();
// Set some content to print

代碼輸出的PDF文件瀏覽器。我如何將pdf數據保存到數據庫或以其他方式保存到文件系統?對於文本數據,我已經使用file_put_contents來創建html/txt文件。
解決了感謝Piskvor。 解決方案代碼
$content=$pdf->Output('', 'S');
header("Content-type:application/pdf");
header("Content-Disposition:attachment;filename='pdf.pdf'");
echo $content;
可以節省$內容在您的分貝斑點和檢索它來生成PDF文件。如果您希望在瀏覽器中打開pdf,請刪除以下行。
header(「Content-Disposition:attachment; filename ='pdf.pdf'」);
你的問題是什麼?另外,你確定這是一個好主意嗎? – 2010-08-20 09:21:15

我明白,存儲blob可能不是一個好主意,但將pdf存儲到文件系統意味着在備份期間也必須管理pdf發票文件夾。將它存儲爲blob意味着我有一件事情可以管理。 – abel 2010-08-20 09:28:27
