Features
- Opening and unzipping zip files.
- Creating ZIP-archives.
- Modifying ZIP archives.
- Pure php (not require extension
php-zip
and class\ZipArchive
). - It supports saving the archive to a file, outputting the archive to the browser, or outputting it as a string without saving it to a file.
- Archival comments and comments of individual entry are supported.
- Get information about each entry in the archive.
- Only the following compression methods are supported:

Attention!
For 32-bit systems, the
Traditional PKWARE Encryption (ZipCrypto)
encryption method is not currently supported. Use the encryption methodWinZIP AES Encryption
, whenever possible.- Set the password to read the archive for all entries or only for some.
- Change the password for the archive, including for individual entries.

Creation/Opening of ZIP-archive
ZipFile::__construct**
Initializes the ZIP archive
$zipFile = new \PhpZip\ZipFile();
ZipFile::openFile
Opens a zip-archive from a file.
$zipFile = new \PhpZip\ZipFile(); $zipFile->openFile('file.zip');
ZipFile::openFromString
Opens a zip-archive from a string.
$zipFile = new \PhpZip\ZipFile(); $zipFile->openFromString($stringContents);
ZipFile::openFromStream
Opens a zip-archive from the stream.
$stream = fopen('file.zip', 'rb'); $zipFile = new \PhpZip\ZipFile(); $zipFile->openFromStream($stream);
Reading entries from the archive
ZipFile::count
Returns the number of entries in the archive.
$zipFile = new \PhpZip\ZipFile(); $count = count($zipFile); // or $count = $zipFile->count();
ZipFile::getListFiles
Returns list of archive files.
$zipFile = new \PhpZip\ZipFile(); $listFiles = $zipFile->getListFiles(); // example array contents: // array ( // 0 => 'info.txt', // 1 => 'path/to/file.jpg', // 2 => 'another path/', // 3 => '0', // )
ZipFile::getEntryContent
Returns the entry contents using its name.
// $entryName = 'path/to/example-entry-name.txt'; $zipFile = new \PhpZip\ZipFile(); $contents = $zipFile[$entryName]; // or $contents = $zipFile->getEntryContents($entryName);
ZipFile::hasEntry
Checks if there is an entry in the archive.
// $entryName = 'path/to/example-entry-name.txt'; $zipFile = new \PhpZip\ZipFile(); $hasEntry = isset($zipFile[$entryName]); // or $hasEntry = $zipFile->hasEntry($entryName);
ZipFile::isDirectory
Checks that the entry in the archive is a directory.
// $entryName = 'path/to/'; $zipFile = new \PhpZip\ZipFile(); $isDirectory = $zipFile->isDirectory($entryName);
ZipFile::extractTo
Extract the archive contents. The directory must exist.
$zipFile = new \PhpZip\ZipFile(); $zipFile->extractTo($directory);
Extract some files to the directory. The directory must exist.
// $toDirectory = '/tmp'; $extractOnlyFiles = [ 'filename1', 'filename2', 'dir/dir/dir/' ]; $zipFile = new \PhpZip\ZipFile(); $zipFile->extractTo($toDirectory, $extractOnlyFiles);
Iterating entries
ZipFile
is an iterator.
Can iterate all the entries in the foreach
loop.
foreach($zipFile as $entryName => $contents){ echo "Filename: $entryName" . PHP_EOL; echo "Contents: $contents" . PHP_EOL; echo '-----------------------------' . PHP_EOL; }
Can iterate through the Iterator
.
$iterator = new \ArrayIterator($zipFile); while ($iterator->valid()) { $entryName = $iterator->key(); $contents = $iterator->current(); echo "Filename: $entryName" . PHP_EOL; echo "Contents: $contents" . PHP_EOL; echo '-----------------------------' . PHP_EOL; $iterator->next(); }
Getting information about entries
ZipFile::getArchiveComment
Returns the Zip archive comment.
$zipFile = new \PhpZip\ZipFile(); $commentArchive = $zipFile->getArchiveComment();
ZipFile::getEntryComment
Returns the comment of an entry using the entry name.
$zipFile = new \PhpZip\ZipFile(); $commentEntry = $zipFile->getEntryComment($entryName);
Adding entries to the archive
All methods of adding entries to a ZIP archive allow you to specify a method for compressing content.
The following methods of compression are available:
\PhpZip\Constants\ZipCompressionMethod::STORED

Working with entries and archive
ZipFile::rename
Renames an entry defined by its name.

ZipFile::setCompressionLevel
Set the compression level for all files in the archive.
Note that this method does not apply to entries that are added after this method is run.
By default, the compression level is 5 (\PhpZip\Constants\ZipCompressionLevel::NORMAL
) or the compression level specified in the archive for Deflate compression.
The values range from 1 (\PhpZip\Constants\ZipCompressionLevel::SUPER_FAST
) to 9 (\PhpZip\Constants\ZipCompressionLevel::MAXIMUM

$zipFile = new \PhpZip\ZipFile(); $zipFile->setCompressionLevel(\PhpZip\Constants\ZipCompressionLevel::MAXIMUM);
ZipFile::setCompressionLevelEntry
Sets the compression level for the entry by its name.
The values range from 1 (\PhpZip\Constants\ZipCompressionLevel::SUPER_FAST
) to 9 (\PhpZip\Constants\ZipCompressionLevel::MAXIMUM
) are supported. The higher the number, the better and longer the compression.
$zipFile = new \PhpZip\ZipFile(); $zipFile->setCompressionLevelEntry($entryName, \PhpZip\Constants\ZipCompressionLevel::FAST);
ZipFile::setCompressionMethodEntry
Sets the compression method for the entry by its name.
The following compression methods are available:
\PhpZip\Constants\ZipCompressionMethod::STORED

ZipFile::setArchiveComment
Set the comment of a ZIP archive.
$zipFile = new \PhpZip\ZipFile(); $zipFile->setArchiveComment($commentArchive);
ZipFile::setEntryComment
Set the comment of an entry defined by its name.
$zipFile = new \PhpZip\ZipFile(); $zipFile->setEntryComment($entryName, $comment);
ZipFile::matcher
Selecting entries in the archive to perform operations on them.
$zipFile = new \PhpZip\ZipFile(); $matcher = $zipFile->matcher();
Selecting files from the archive one at a time:
$matcher ->add('entry name') ->add('another entry');
Select multiple files in the archive:
$matcher->add([ 'entry name', 'another entry name', 'path/' ]);
Selecting files by regular expression:
$matcher->match('~\.jpe?g$~i');
Select all files in the archive:
$matcher->all();
count() - gets the number of selected entries:
$count = count($matcher); // or $count = $matcher->count();
getMatches() - returns a list of selected entries:
$entries = $matcher->getMatches(); // example array contents: ['entry name', 'another entry name'];
invoke() - invoke a callable function on selected entries:
// example $matcher->invoke(static function($entryName) use($zipFile) { $newName = preg_replace('~\.(jpe?g)$~i', '.no_optimize.$1', $entryName); $zipFile->rename($entryName, $newName); });
Functions for working on the selected entries:
$matcher->delete(); // remove selected entries from a ZIP archive $matcher->setPassword($password); // sets a new password for the selected entries $matcher->setPassword($password, $encryptionMethod); // sets a new password and encryption method to selected entries $matcher->setEncryptionMethod($encryptionMethod); // sets the encryption method to the selected entries $matcher->disableEncryption(); // disables encryption for selected entries
Working with passwords
Implemented support for encryption methods:
\PhpZip\Constants\ZipEncryptionMethod::PKWARE
- Traditional PKWARE encryption (legacy)\PhpZip\Constants\ZipEncryptionMethod::WINZIP_AES_256
- WinZip AES encryption 256 bit (recommended)\PhpZip\Constants\ZipEncryptionMethod::WINZIP_AES_192
- WinZip AES encryption 192 bit\PhpZip\Constants\ZipEncryptionMethod::WINZIP_AES_128
- WinZip AES encryption 128 bit
ZipFile::setReadPassword
Set the password for the open archive.
Setting a password is not required for adding new entries or deleting existing ones, but if you want to extract the content or change the method / compression level, the encryption method, or change the password, in this case the password must be specified.
$zipFile->setReadPassword($password);
ZipFile::setReadPasswordEntry
Gets a password for reading of an entry defined by its name.
$zipFile->setReadPasswordEntry($entryName, $password);
ZipFile::setPassword
