我想提供下载发票.目前我使用的是简单的编号方案(invoice-01.pdf,invoice-02.pdf等).我知道我可以使用哈希来掩盖数据.
在
php.net甚至有一个例子
@H_301_7@<?PHP
// We'll be outputting a PDF
header('Content-type: application/pdf');
// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');
// The PDF source is in original.pdf
readfile('original.pdf');
?>
或者扩展一下
@H_301_7@<?PHP if ( can_this_file_be_downloaded() ) { header('Content-type: application/pdf'); header('Content-Disposition: attachment; filename="invoice.pdf"'); readfile("{$_GET['filename']}.pdf"); } else { die("None shall pass"); } ?>
