PHP & downloading files

[berbbrown]

I place this problem on the other day but didn't get much help so here goes again. H E L P !!

What is the best method to download files of any type. If tried the following PHP code and it works but PDF's do not.

[FONT=courier new]
$TheFileSize = filesize($strFullDownloadFilename);

if (strstr($HTTP_USER_AGENT, "MSIE")) {
$Attachment = "";
} else {
$Attachment = " attachment;";
}

header("Cache-control: private"); // fix for IE
header("Content-type: application/force-download");
header("Content-Disposition: $Attachment filename=\"$TheFilename\"");
header("Content-Description: $FileDescription");
header("Content-Length: $TheFileSize");
header("Content-Transfer-Encoding: binary");
set_time_limit(0);
readfile($strFullDownloadFilename);
[/FONT]

Thanks

I'm using this one, working with pdf, too:

	header('Content-Type: application/octet-stream');
	header('Content-Length: '.filesize($filename));

global $HTTP_USER_AGENT;
if (preg_match('/MSIE 5.5/', $HTTP_USER_AGENT) || preg_match('/MSIE 6.0/', $HTTP_USER_AGENT))
{
	header('Content-Disposition: filename="'.$saveasname.'"');
}
else
{
	header('Content-Disposition: attachment; filename="'.$saveasname.'"');
}
header('Content-Transfer-Encoding: binary');
readfile($filename);

How do you force the file to be downloaded?

I can get it to work for most files but for a PDF I have to change the:

[FONT=courier new]
header("Content-type: application/force-download");
[/FONT]

to the correct MIME type for a PDF and then it opens Acrobat Read directly.

It only seems to do with IE, Navigator prompts you to save it.

Also what is better Readfile or Fopen?

like I said, my code works for me 😕

what does it say when you're using "application/octet-stream" ?

readfile() reads the content into a string, fopen() creates a filehandler

hence, these functions can't be compared !!
