Question

I have lots of files in a particular Directory. In a certain PHP page I lists the contents of the particular directory with links to download each item separately. Now I need to display a Link which will ZIP all the contents of that directory so any visitor can download all the contents as a Single ZIP file.

Answer 1

Use ZipArchive for zipping files and RecursiveDirectoryIterator for getting all files in a directory

something like

$zipfilename = <zip filename>;
$zip = new ZipArchive();
$zip->open($zipfilename, ZipArchive::CREATE);
// add all files in directory to zip
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator('path/to/files/')) as $filename) {
    $zip->addFile($filename);
}
$zip->close();

Then send the zip to the browser

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename="'. $zipfilename .'"');
header('Content-Length: ' . filesize($zipfilename));
readfile($zipfilename);

Obviously you could post the directory name and event the zip file name to the script but it gives you a starting point
