php-如何创建受密码保护的pdf文件
作者:互联网
我正在使用html2fpdf创建PDF文档.现在,一旦我创建了该文件,就想确保PDF文件受密码保护.如何在PHP中完成?
解决方法:
从a blog post on the ID Security Suite site下载我正在使用的库:
<?php
function pdfEncrypt ($origFile, $password, $destFile){
require_once('FPDI_Protection.php');
$pdf =& new FPDI_Protection();
$pdf->FPDF('P', 'in');
//Calculate the number of pages from the original document.
$pagecount = $pdf->setSourceFile($origFile);
//Copy all pages from the old unprotected pdf in the new one.
for ($loop = 1; $loop <= $pagecount; $loop++) {
$tplidx = $pdf->importPage($loop);
$pdf->addPage();
$pdf->useTemplate($tplidx);
}
//Protect the new pdf file, and allow no printing, copy, etc. and
//leave only reading allowed.
$pdf->SetProtection(array(), $password);
$pdf->Output($destFile, 'F');
return $destFile;
}
//Password for the PDF file (I suggest using the email adress of the purchaser).
$password = "testpassword";
//Name of the original file (unprotected).
$origFile = "sample.pdf";
//Name of the destination file (password protected and printing rights removed).
$destFile ="sample_protected.pdf";
//Encrypt the book and create the protected file.
pdfEncrypt($origFile, $password, $destFile );
?>
