I'm new to SO and new to PHP. I found a script online to zip a directory and I've edited it so that it sends the zip to the browser for download and then deletes the file from the server.
It works fine, however I would like to zip multiple directories instead of just one.
How would I need to alter my script to accomplish this?
$date = date('Y-m-d');
$dirToBackup = "content";
$dest = "backups/"; // make sure this directory exists!
$filename = "backup-$date.zip";
$archive = $dest.$filename;
function folderToZip($folder, &$zipFile, $subfolder = null) {
if ($zipFile == null) {
// no resource given, exit
return false;
}
// we check if $folder has a slash at its end, if not, we append one
$folder .= end(str_split($folder)) == "/" ? "" : "/";
$subfolder .= end(str_split($subfolder)) == "/" ? "" : "/";
// we start by going through all files in $folder
$handle = opendir($folder);
while ($f = readdir($handle)) {
if ($f != "." && $f != "..") {
if (is_file($folder . $f)) {
// if we find a file, store it
// if we have a subfolder, store it there
if ($subfolder != null)
$zipFile->addFile($folder . $f, $subfolder . $f);
else
$zipFile->addFile($folder . $f);
} elseif (is_dir($folder . $f)) {
// if we find a folder, create a folder in the zip
$zipFile->addEmptyDir($f);
// and call the function again
folderToZip($folder . $f, $zipFile, $f);
}
}
}
}
// create the zip
$z = new ZipArchive();
$z->open($archive, ZIPARCHIVE::CREATE);
folderToZip($dirToBackup, $z);
$z->close();
// download the zip file
$file_name = basename($archive);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Length: " . filesize($archive));
readfile($archive);
// delete the file from the server
unlink($archive);
exit;
Thanks for any help!
