PHP – How user can set directory where downloaded file will be saved?

I am making a simple application in which the user uploads files using 2 HTML input:file fields and a zip archive is created from them. Is there any way I can let the user choose where this zip can go? (Something like a "Save As" window).

This is my current solution, which saves archive only to default download destination without asking.

    $files = array($_FILES["fileone"]["name"], $_FILES["filetwo"]["name"]);
    $zipname = "myarchive.zip";
    $zip = new ZipArchive;
    $zip->open($zipname, ZipArchive::CREATE);
    foreach ($files as $file) {
        $zip->addFile($file);
    }
    $zip->close();

    header('Content-Type: application/zip');
    header('Content-disposition: attachment; filename='.$zipname);
    header('Content-Length: ' . filesize($zipname));
    header("Pragma: no-cache"); 
    header("Expires: 0"); 
    readfile($zipname);

>Solution :

It is not possible for a PHP script to prompt the user for a location to save a file. This kind of functionality is typically handled by the user’s web browser.

However, you can provide a download link for the file that the user can click on to download the file. When the user clicks on the link, their web browser will prompt them to choose a location to save the file.

Here is an example of how you could provide a download link for the zip file that your PHP script creates:

$files = array($_FILES["fileone"]["name"], $_FILES["filetwo"]["name"]);
$zipname = "myarchive.zip";
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
    $zip->addFile($file);
}
$zip->close();

// Provide a link for the user to download the zip file
echo '<a href="' . $zipname . '">Click here to download the zip file</a>';

When the user clicks on the link, their web browser will prompt them to choose a location to save the file.

Note: If you want to force the web browser to download the file instead of opening it, you can use the Content-Disposition HTTP header. Here is an example of how you could set this header to force the file to download:

header('Content-Disposition: attachment; filename="' . $zipname . '"');

This will tell the web browser to download the file and save it with the specified filename, instead of opening it.
