File Save

[Anon]

Hi,

I'm trying to make a bit of code that when a user presses a button on the page a file is saved to their local hard disk. I'm failing to figure this one out and i was wondering if anyone had any ideas. It would be under PHP4.

Thanx

Tom

Well, since you page is running in a browser, you don't have direct access to the visitor's hard drive. The best you can do is make the "button" a link to the file you want them to download. They will still be asked by their browser if and where they want to save the file, however.

What kind of file is it? A mime-type or content-type header will usually cause the browser to react correctly. Say you download an EXE under Windows... IE recognizes the content-type as an application and prompts you to save the EXE or run it directly. If you're dynamically generating content using PHP for download, you can specify your own content-type. For instance, if you were streaming a zip file back to the user

<? php
header("content-type: application/x-zip");
$fd = fopen(...some zip file...);
// fpassthru the file
fclose($fd);
?>

See this page for some general concepts:
