ZipArchive::addEmptyDir
Here's a little extension to ZipArchive that handles directories recursively:
<?php
class Zipper extends ZipArchive {
public function addDir($path) {
print 'adding ' . $path . '<br>';
$this->addEmptyDir($path);
$nodes = glob($path . '/*');
foreach ($nodes as $node) {
print $node . '<br>';
if (is_dir($node)) {
$this->addDir($node);
} else if (is_file($node)) {
$this->addFile($node);
}
}
}
} // class Zipper
?>
ZipArchive::addFile
(PHP 5 >= 5.2.0, PECL zip >= 1.1.0)
ZipArchive::addFile — Adds a file to a ZIP archive from the given path
Description

( string $filename
[, string $localname
] )
Adds a file to a ZIP archive from a given path
Parameters
- filename
-
The path to the file to add.
- localname

local name inside ZIP archive.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt.
Example #1 Open and extract
<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {

If you have some warnings with ZipArchiveImproved since the last Ubuntu update, replace "self::CREATE" by "self::CREATE | self::OVERWRITE" in the reopen function

If you add files that have an absolut path, like for example:
/mnt/repository/my_file.pdf
the standard windows zip utility will not be able to extract the files. The first slash trips the zip utility. You have to add relative file paths or use a symbolic link.

Note that the file isn't actually added to the archive until the $zip->close() method is called. I spent a lot of time trying to figure out why no time() went by after adding large files via $zip->addFile() but would then time out the script.

here is a basic class that extends the ZipArchive to:
* add a functionality to report the ZIP file address (I needed it and I could not find out how in ZipArchive documentation).
* resolve the problem of adding so many files to the archive due file descriptor limit. the ZipArchiveImproved::addFile() handles this.
<?php
/**

This is my workaround for the file descriptor limit by closing/opening the archive file periodically.
<?php
if($backup = new ZipArchive()) {
if($backup->open($zip, ZIPARCHIVE::OVERWRITE) === true) {
$backup->addFile($file['realpath'], $file['path']);
if(($count++) == 200) { // the file descriptor limit
$backup->close();
if($backup = new ZipArchive()) {
$backup->open($zip);
$count = 0;
}
}
}
$backup->close();
}
?>
Hope it helps someone.

I have had several problems trying adding files, because of a path problem. The error gived was this:
ZipArchive::addFile() [function.ZipArchive-addFile]: Unable to access <path>
I used an absolute root starting by "/", and it didn't work. Try starting your path with "./" (referencing the root of your site).

The workaround above (file_get_contents) is very dangerous if you pack large files. (see memory limit).
Close/open the zip archive periodically instead of using file_get_contents().

It should be noted that the example provided above is not accurate.
Unlike extractTo, zip_open does not return a boolean result, so the above example will always fail.

What is worse is that when you run out of filedescriptors it seems to fail silently, I have not been able to find any errors in any logfiles.

Currently the number of files that can be added using addFile to the ZIP archive (until it is closed) is limited by file descriptors limit. This is an easy workaround (on the bug links below you can find another workarounds):
<?php
/** work around file descriptor number limitation (to avoid failure
* upon adding more than typically 253 or 1024 files to ZIP) */
function addFileToZip( $zip, $path, $zipEntryName ) {
// this would fail with status ZIPARCHIVE::ER_OPEN
// after certain number of files is added since
// ZipArchive internally stores the file descriptors of all the
// added files and only on close writes the contents to the ZIP file
// see: http://bugs.php.net/bug.php?id=40494
// and: http://pecl.php.net/bugs/bug.php?id=9443
// return $zip->addFile( $path, $zipEntryName );
$contents = file_get_contents( $path );
if ( $contents === false ) {
return false;
}
return $zip->addFromString( $zipEntryName, $contents );
}
?>
