使用 header() 重写 URL 中的文件名以获取动态 pdf

我有一个生成 pdf 报告的 php 脚本.当我们去保存pdf文档时，Acrobat建议的文件名是report_pdf，因为php脚本被命名为report_pdf.php.我想动态命名 pdf 文件，所以我不必在每次保存报告时键入适当的名称.

I have a php script that generates a pdf report. When we go to save the pdf document, the filename that Acrobat suggests is report_pdf, since the php script is named report_pdf.php. I would like to dynamically name the pdf file, so I don't have to type the appropriate name for the report each time that I save it.

询问新闻组，有人建议这样做，其中 filename="July Report.pdf" 是报告的预期名称

Asking on a news group, someone suggested this, where filename="July Report.pdf" is the intended name of the report

<?
header('Content-Type: application/pdf');
header('Content-disposition: filename="July Report.pdf"');

但它不起作用.我做错了吗，或者这会起作用吗?这是 mod_rewrite 的工作吗?

But it doesn't work. Am I doing it wrong, or will this work at all? Is this a job for mod_rewrite?

所以我都试过了

header('Content-disposition: inline; filename="July Report.pdf"');

和

header('Content-disposition: attachment; filename="July Report.pdf"');

(不是同时)而且都不适合我.这是我的网络主机的问题吗?对于这个 url，这是我的代码:

( not at the same time ) and neither work for me. Is this a problem with my web host? For this url, here's my code:

<?
header('Content-disposition: inline; filename="July Report.pdf"');

// requires the R&OS pdf class
require_once('class.ezpdf.php');
require_once('class.pdf.php');

// make a new pdf object
$pdf = new Cpdf();
// select the font
$pdf->selectFont('./fonts/Helvetica');
$pdf->addText(30,400,30,'Hello World');
$pdf->stream();

?>
