filepathThe path to the file to add.
entryname
If supplied and not empty, this is the local name inside the ZIP archive that will override the filepath.
startFor partial copy, start position.

For partial copy, length to be copied,
if ZipArchive::LENGTH_TO_END (0) the file size is used,
if ZipArchive::LENGTH_UNCHECKED the whole file is used
(starting from start).
flags
Bitmask consisting of
ZipArchive::FL_OVERWRITE,
ZipArchive::FL_ENC_GUESS,
ZipArchive::FL_ENC_UTF_8,
ZipArchive::FL_ENC_CP437,
ZipArchive::FL_OPEN_FILE_NOW.

This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt.
Example #1 Open and add
<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
$zip->addFile('/path/to/index.txt', 'newname.txt');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
?>Nota:
When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close() or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released.
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);
?>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.The manual is lying.
"In short, it means you can first delete an added file after the archive is closed. "
Thats true but not by locking the file...
Warning! This method works asynchronous!
It seems that addFile() will return TRUE if the file stat command returns correctly, but the operation itself will not happen yet.
Instead, deleting a file is always possible. I have discovered this behaviour by using a temporary file and deleting it immediately after addFile() returns. The result was that no archive was created nor any file was added although every operation (creating,open(),addFile()) returned true before. The operation silenty fails.If you have problem with windows explorer reading zipfile created by linux, try:
$oZip->addFile ( $file_name, " " . basename ( $file_name ) )
That space " " should solve.there are some points can be more clear, it take me some time to figure out. hope it can help you.
1.use addFile() ,method to add the file with path to zip. if the directory not exist, addFile() would auto create it.
<?php
....
//addFile would help you create the directory named not_exist_director before add the filename.txt file.
$zip->addFile($fileToAdd, '/not_exist_directory/filename.txt');
...
?>
2. addFile() would overwrite the old file if exist in default.
<?php
....
//if the filename.txt is exist in the zip, addFile() would overwrite it. because the the addFile fifth param is ZipArchive::FL_OVERWRITE by default.
$zip->addFile($fileToAdd, '/filename.txt');
...
?>2 tips:
- The example in on this page is a bit misleading for new programmers. It works only if the ZIP archive file exists already. Don't forget to use ZipArchive::CREATE and optionally ZipArchive::OVERWRITE in the second optional parameter in the open() function.
- If you want to add files and directories recursively (see some examples from other comments here on this page) use scandir() instead of blob() because blob() does not list hidden files like ".htaccess" for example.In some versions of this library you NEED to add the "localfile" parameter or the file will not show in the Zip folder.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().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.work 4 me

GioMBGOn 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.Note that using addFile() will change the order of the files within the zip, in fact within the index of the zip. Does not matter much, except if you loop the index and use addFile() within that loop : it will likely give messy results.
Example :
<?php
$zip = new ZipArchive;
if ($zip->open('somefile.zip') === TRUE) {
for ($i = 0; $i < $zip->numFiles; $i++) {
if (forsomereason()) {
addFile('./somenewfile.ext', $zip->getNameIndex($i));
}
}
}
$zip->close();
?>
This code may loop for ever, depending on your forsomereason() function, or at least you're at risk.
Try something like this instead :
<?php
$zip = new ZipArchive;
if ($zip->open('somefile.zip') === TRUE) {
for ($i = 0; $i < $zip->numFiles; $i++) {
if (forsomereason()) {
$couples[]=array('filename'=>'./somenewfile.ext','localname'=>$zip->getNameIndex($i));
}
}
}
foreach ($couples as $couple) $zip->addFile($couple['filename'],$couple['localname']);
$zip->close();
?>
Hope it helps ;-)I had a huge number of files and folders that I needed to zip on a linux web server. I was running into timeout problems and file enumerator issues, as well as file handler limit issues (ulimit). I used a script to solve u limit offered by Farzad Ghanei first (ZipArchiveImproved), but closing and reopening his way didn't do the trick for me.
I eventually did a simple call to a $filelimit variable I created that records file handler limit I want my script to hit before it closes and reopens the file.
<?php
$filelimit = 255;
if ($zip->numFiles == $filelimit) {$zip->close(); $zip->open($file) or die ("Error: Could not reopen Zip");}
?>
This made some progress for me, timeouts were gone, but when calling
<?php $zip->addFile($filepath, $archivefilepath); ?>
after the reopening of the Zip, I got an error. I echoed the <?php $zip->numFiles; ?> and found that after reopening, the numFile enum reset to '0'.
A few more goose-chases later, I tried addFromString with some better results, but did not get it working 100% until I actually coupled addFromString with addFile! My working scripting for the add files function on massive file-folder structures looks like so:
<?php
$sourcefolder = /rel/path/to/source/folder/on/server/
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
//how many file can be added before a reopen is forced?
$filelimit = 245;
// Defines the action
$file = tempnam("tmp", "zip");
$zip = new ZipArchive();
// This creates and then gives the option to save the zip file
if ($zip->open($file, ZipArchive::OVERWRITE) !== TRUE) {
die ("Could not open archive");
}
// adds files to the file list
foreach ($filelist as $key=>$value) {
//fix archive paths
$path = str_replace($sourcefolder, "", $key); //remove the source path from the $key to return only the file-folder structure from the root of the source folder
if (!file_exists($key)) { die($key.' does not exist. Please contact your administrator or try again later.'); }
if (!is_readable($key)) { die($key.' not readable. Please contact your administrator or try again later.'); }
if ($zip->numFiles == $filelimit) {$zip->close(); $zip->open($file) or die ("Error: Could not reopen Zip");}
$zip->addFromString($path, $key) or die ("ERROR: Could not add file: $key </br> numFile:".$zip->numFiles);
$zip->addFile(realpath($key), $path) or die ("ERROR: Could not add file: $key </br> numFile:".$zip->numFiles);
}
// closes the archive
$zip->close();
//make local temp file a .zip, rename, and move to output dir
rename ($file, "./" . $outputfolder . "/" . $zipfilename);
?>
I hope this may help someone else.Here's a little extension to ZipArchive that handles directories recursively:
<?php
class Zipper extends ZipArchive {
public function addDir($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
?>Do NOT use ZipArchive::addFile() to append a folder.
When a folder's path is passed to ZipArchive::addFile(), the method returns true, but ZipArchive can neither create a zip archive nor can it make any change to a existing file.
<?php
$z = new ZipArchive();
if(true === ($z->open('./foo.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE))){
$z->setArchiveComment('Interesting!');
$z->addFromString('domain.txt', 'wuxiancheng.cn');
$folder = './test';
!is_dir($folder) && mkdir($folder); // Create an folder for testing
if(true === $z->addFile($folder)){
echo 'success'; // !!!
}
rmdir($folder);
$z->close();
// foo.zip will NOT be saved on disk.
// If foo.zip already exists before we run this script, the file will remain unchanged.
}
?>As others have pointed out ZipArchive::addFile() is asynchronous. If you want to restrict the time when adding a large number of files this is the way to do it:
<?php
//$files is an array with a horrendous amount of filenames.
//$fileCount the total number of files in $files e.q. count($files)
//$fileIndex is the file you want to start with
for(
$fileIndex = 1, $start = hrtime( true );
$fileIndex < $fileCount and $secondsElapsed < 5.0;
$fileIndex++
) {
$currentfile = $files[ $fileIndex ];
if( file_exists( $currentfile ) ) {
$zip->addFile( $currentfile );
usleep(1);
$secondsElapsed = ( hrtime( true ) - $start ) / 1e+9;
}
}
?>
this will keep on adding files until the time out (5.0s) arises. Without usleep(1) it will just continue until the max_excecution_time is reached.zip->addfile function does not add file to archive immediately. It is cued and executed at zip->close()
I had backup files in a dir. with a foreach statement I was adding the file to an archive and then moving the files into dump dir immediately.
This caused an error.
<?php
$dir = getcwd().'/';
$dirContent = scandir('./');
foreach($dirContent as $file)
if(strpos($file, '.sql')!==false)
{
echo "adding $file ......";
$zip->addFile($file);
$newFileName = $dir."done/$file";
rename($dir.$file, $newFileName);
echo( "; file added\n");
}
$zip->close();
?>
The $zip->close() needs to execute before moving files,
<?php
foreach($dirContent as $file)
if(strpos($file, '.sql')!==false)
{
echo "adding $file ......";
$zip->addFile($file);
echo( "; file added\n");
}
$zip->close();
foreach($dirContent as $file)
if(strpos($file, '.sql')!==false)
{
$newFileName = $dir."done/$file";
rename($dir.$file, $newFileName);
echo( "$file moved\n");
}

?>The addFile() method does not accept the "file://" protocol. Strip away "file://" and use the absolute path instead.
I assume that it also does not accept any other protocols, I was having issues trying to add files, other functions within the application I was building required the use of the protocol.
Also to note, the status code returned did not match any of the predefined error codes, and the status code was never the same. My assumption was a overflow on the variable as the status codes were around the minimum and maximum INT values.Note that there is no concept of "folders" for ZIP files. If you need to store data into folders, use forward slashes ("/") in $localname to separate folder(s) and the file name.
Example:
$zip->addFile("test.txt", "mainfolder/subfolder/test.txt");This add directory function does not require that you create a new wrapper class, and also does not add the entire file directory tree into your zip file.
<?php
public function addDirectoryToZip($zip, $dir, $base)
{
$newFolder = str_replace($base, '', $dir);
$zip->addEmptyDir($newFolder);

recursively adds all directories and files within a directory

}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, $contents );
}
?>Another surprise, which took a lot of trouble. So that after you add a file to the archive it can be safely removed, took advantage of such construction:
if (!is_file ($archive)) :
$result = $zip->open ($archive, ZipArchive::CREATE);
else :
$result = $zip->open ($archive);
endif;
if ($result === TRUE) :
if (($zip->addFile ($file, $filename)) === TRUE) :
$theoreticaly_added = TRUE;
endif;
if ((($zip->close ()) === TRUE) && $theoreticaly_added) :
unlink ($file);
endif;
endif;
Now the files will not disappear. But perhaps there is a simpler solution, which gives 100% guarantee?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).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.如果文件名包含汉字，ZIPARCHIVE::addFile() 会导致无法将文件压缩到压缩包中，或者压缩以后文件名乱码。
可以使用ZipArchive::addFromString()来实现。
注意：如果操作系统是Windows，文件系统编码是gbk.
如果php文件的文件编码是utf-8，需要相应转码。
ZipArchive::addFile() fails if the filename contains Chinese characters.
ZipArchive::addFromString() should be used instead.
<?php
$z = new ZipArchive;
$file = '吴先成.txt';
if($z->open(ZIPARCHIVE::CREATE)===true){
$z->addFromString($file, file_get_contents($file));
//for windows
//$z->addFromString($file, file_get_contents(iconv('utf-8', 'gbk//ignore', $file)));
}
// ...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.Note that ZipArchive::open() not return boolean value, but integer, for example :
$zip = new ZipArchive();
$filename = '/tmp/test.zip';
var_dum($zip->open($filename)); // return's : int (11)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.<?php
$zip=new ZipArchive;
$zip->addFile('path to the file', 'new name of the file');
?>
What I have to do, when I wan't to have the file in the zip archive with it's name before archiving?
(Sorry, I'm from Czech Republic and I can't speak English very well, if I did anywhere mistake, so ignore that pease :-)This is my workaround for the file descriptor limit by closing/opening the archive file periodically.
<?php
if($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.
