ZipArchive::addEmptyDir
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 );
}
?>
