ZipArchive::addFile — Fügt eine Datei von einem gegebenen Pfad zu einem ZIP-Archiv hinzu
Fügt eine Datei von einem gegebenen Pfad zu einem ZIP-Archiv hinzu.
Der Pfad zur hinzuzufügenden Datei.
Lokaler Name innerhalb des ZIP-Archivs.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Dieses Beispiel öffnet ein ZIP-Dateiarchiv test.zip und fügt die Datei /pfad/zur/datei.txt als neuername.txt hinzu.
Beispiel #1 Öffnen und extrahieren
<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
$zip->addFile('/pfad/zur/datei.txt', 'neuername.txt');
$zip->close();
echo 'ok';
} else {
echo 'Fehler';
}
?>
Beware: calling $zip->addFile() on a file that doesn't exist will succeed and return TRUE, delaying the failure until you make the final $zip->close() call, which will return FALSE and potentially leave you scratching your head.
If you're adding multiple files to a zip and your $zip->close() call is returning FALSE, ensure that all the files you added actually exist.
It's also a good idea to check each file with file_exists() or is_readable() before calling $zip->addFile() on it.
When adding a file to your zip, the file is opened and stays open.
When adding over 1024 files (depending on your open files limit) the server stops adding files, resulting in a status 11 in your zip Archive. There is no warning when exceeding this open files limit with addFiles.
Check your open files with ulimit -a
This kept me busy for some time.
In some versions of this library you NEED to add the "localfile" parameter or the file will not show in the Zip folder.
<?php
$zip=new ZipArchive;
$zip->addFile('path to the file', 'new name of the file');
?>
What I have to do, when I wan't to have the file in the zip archive with it's name before archiving?
(Sorry, I'm from Czech Republic and I can't speak English very well, if I did anywhere mistake, so ignore that pease :-)
It is not obvious, since there are no noticeable examples around, but you can use $localname (second parameter) to define and control file/directory structure inside the zip. Use it if you do not want files to be included with their absolute directory tree.
<?php
$zip->addFile($abs_path, $relative_path);
?>
On my system (Windows), I found that ZipArchive uses IBM850 encoding for filenames (localname). For filenames with special characters such as (é) é which appears at 0xE9 in the ISO-8859-1, it is at 0x82 in IBM850. I had to call iconv('ISO-8859-1', 'IBM850', 'Québec') to get correct file names.
Here's a little extension to ZipArchive that handles directories recursively:
<?php
class Zipper extends ZipArchive {
public function addDir($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
?>
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 );
}
?>
