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();
?>

I have modified thomas dot rubbert at yahoo dot de a little bit
$uploads_dir =storage_path().'/app/public/files/' ;
if(!file_exists($uploads_dir)){
mkdir($uploads_dir,0777,true);
}
$zip_file=$uploads_dir.'download.zip';
if(file_exists($zip_file)){
unlink($zip_file);
}
$zip = new \ZipArchive();
if (!$zip->open($zip_file, \ZIPARCHIVE::CREATE)) {
http_response_code(501);
echo 'Zip creation failed';
die();
}
$img=$uploads_dir.'img';
$dirName = realpath($img);
if (substr($dirName, -1) != DIRECTORY_SEPARATOR) {
$dirName.= DIRECTORY_SEPARATOR;
}
$dirStack = array($dirName);
//Find the index where the last dir starts
$cutFrom = strrpos(substr($dirName, 0, -1), DIRECTORY_SEPARATOR)+1;
while (!empty($dirStack)) {
$currentDir = array_pop($dirStack);

}
if (is_file($currentDir . $node)) {
$filesToAdd[] = $node;
}
}
$localDir =str_replace(DIRECTORY_SEPARATOR,'/',substr($currentDir, $cutFrom));
$zip->addEmptyDir($localDir);
foreach ($filesToAdd as $file) {
$zip->addFile($currentDir . $file, $localDir . $file);
}
}
// any additional files
$db=$uploads_dir.'databse.db';
//$zip->addFromString(basename($db), file_get_contents($db));
$zip->addFile($db, basename($db));
$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
http://bugs.php.net/bug.php?id=40494

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

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 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 :)
