Borrowing from the always brilliant Mr. David Walsh, here is a great little function to create a zip file archive of a given set of files, ready for download from your site. First, the zip file create function which will be doing all the heavy lifting: function create_zip($files = array(), $destination = ”, $overwrite = false) { //if the zip file already exists and overwrite is false, return false if (file_exists($destination) && !$overwrite) { return false; } //vars $valid_files = array(); //if files were passed in… if (is_array($files)) { //cycle through each file foreach ($files as $file) { //make sure the file exists if (file_exists($file)) { $valid_files[] = $file; } } } //if we have good files… if (count($valid_files)) { //create the archive $zip = new ZipArchive(); if ($zip->open($destination, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { return false; } //add the files foreach ($valid_files as $file) { $zip->addFile($file, basename($file)); } //debug //echo ‘The zip archive contains ‘,$zip->numFiles,’ files with a status of ‘,$zip->status; //close the zip — done! $zip->close(); //check to make sure the file exists return file_exists($destination); } else { return false; } } Right, now that we have the function, let us set about putting it to use. First, we’ll need an array of fully qualified files to use, for example: $filestozip = array( ‘/var/www/uploads/file1.jpg’, ‘/var/www/uploads/file2.jpg’, ‘/var/www/example3.html’ ); Now we simple run the function, providing it with our array of files to be included, the proposed name of the archive we want to generate, as well as [...]
