Add folder and sub-directories to zip archive.
<?php
$archive_name = "archive.zip"; // name of zip file
$archive_folder = "folder"; // the folder which you archivate
$zip = new ZipArchive;
if ($zip -> open($archive_name, ZipArchive::CREATE) === TRUE)
{
$dir = preg_replace('/[\/]{2,}/', '/', $archive_folder."/");
$dirs = array($dir);
while (count($dirs))
{
$dir = current($dirs);
$zip -> addEmptyDir($dir);
$dh = opendir($dir);
while($file = readdir($dh))
{
if ($file != '.' && $file != '..')
{
if (is_file($file))
$zip -> addFile($dir.$file, $dir.$file);
elseif (is_dir($file))
$dirs[] = $dir.$file."/";
}
}
closedir($dh);
array_shift($dirs);
}
$zip -> close();
echo 'Archiving is sucessful!';
}
else
{
echo 'Error, can\'t create a zip file!';
}
?>

I've brought a little modification to dayjo's code, so it wouldn't re-create the whole structure of your working drive in the zip file:
<?php
// Function to recursively add a directory,
// sub-directories and files to a zip archive
function addFolderToZip($dir, $zipArchive, $zipdir = ''){
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
//Add the directory
if(!empty($zipdir)) $zipArchive->addEmptyDir($zipdir);
// Loop through all the files
while (($file = readdir($dh)) !== false) {
//If it's a folder, run the function again!
if(!is_file($dir . $file)){
// Skip parent and root directories
if( ($file !== ".") && ($file !== "..")){
addFolderToZip($dir . $file . "/", $zipArchive, $zipdir . $file . "/");
}
}else{
// Add the files
$zipArchive->addFile($dir . $file, $zipdir . $file);
}
}
}
}
}
?>
If you don't specify the third parameter (zipdir), the directory you're adding will be added at the root of the zip file.

Here's a stack-based way to zip a directory. No recursion, no function, no class:
<?php
$zip = new ZipArchive();
$zip->open('test.zip', ZipArchive::CREATE);
$dirName = 'test';
if (!is_dir($dirName)) {
throw new Exception('Directory ' . $dirName . ' does not exist');
}
$dirName = realpath($dirName);
if (substr($dirName, -1) != '/') {
$dirName.= '/';
}
/*
* NOTE BY danbrown AT php DOT net: A good method of making
* portable code in this case would be usage of the PHP constant
* DIRECTORY_SEPARATOR in place of the '/' (forward slash) above.
*/
$dirStack = array($dirName);
//Find the index where the last dir starts
$cutFrom = strrpos(substr($dirName, 0, -1), '/')+1;
while (!empty($dirStack)) {
$currentDir = array_pop($dirStack);
$filesToAdd = array();
$dir = dir($currentDir);
while (false !== ($node = $dir->read())) {
if (($node == '..') || ($node == '.')) {
continue;
}
if (is_dir($currentDir . $node)) {
array_push($dirStack, $currentDir . $node . '/');
}
if (is_file($currentDir . $node)) {
$filesToAdd[] = $node;
}
}
$localDir = substr($currentDir, $cutFrom);
$zip->addEmptyDir($localDir);
foreach ($filesToAdd as $file) {
$zip->addFile($currentDir . $file, $localDir . $file);
}
}
$zip->close();
?>

addEmptyDir doesn't exist now,
use $zip->addFile($file, $dir.$fichier);
nothing on the net about this,
addEmptyDir work on Ubuntu but not on Debian Etch

There is kind of a bug in the method
ZipArchive::addFile
which affects the class ZipFolder below.
It is related to the numer of max filehandles of the OS.
As workaround add a file-counter to the class and close + reopen the archive if a certain number of files (directories count as files!) is reached.
For more details see here:
http://de.php.net/manual/en/function.ziparchive-addfile.php
or go directly here

On PHP >5.4, This function will create a file, not a directory.
For instance:
$zip->addEmptyDir ( 'path/to/dir/' );
will create the folders "path/", and "path/to/", and a dummy 0-byte file named "dir" in the latter.
If then we add a file to that dir, say like this:
$zip->addFromString ( 'path/to/dir/file.txt', $data );
the result will be a SEPARATE folder named "dir" next to the dummy "dir" file. The "dir" folder will contain the file "file.txt".
This was tested on an APACHE server running PHP 5.4

Here's a simple recurring function to add a directory, all sub-directories and all files to an already created zip file;
<?php
// Function to recursively add a directory,
// sub-directories and files to a zip archive
function addFolderToZip($dir, $zipArchive){
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
//Add the directory
$zipArchive->addEmptyDir($dir);
// Loop through all the files
while (($file = readdir($dh)) !== false) {
//If it's a folder, run the function again!
if(!is_file($dir . $file)){
// Skip parent and root directories
if( ($file !== ".") && ($file !== "..")){
addFolderToZip($dir . $file . "/", $zipArchive);
}
}else{
// Add the files
$zipArchive->addFile($dir . $file);
}
}
}
}
}
?>
Would be nice to see more input on these functions :)
