Glossary

Zip Entry - file or folder in a ZIP-archive. Each entry in the archive has certain properties, for example: file name, compression method, encryption method, file size before compression, file size after compression, CRC32 and others.

Overview of methods of the class \PhpZip\ZipFile

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:

ZipFile::addFile

Adds a file to a ZIP archive from the given path.

$zipFile = new \PhpZip\ZipFile();
// $file = '...../file.ext'; 
// $entryName = 'file2.ext'
$zipFile->addFile($file);

// you can specify the name of the entry in the archive (if null, then the last component from the file name is used)
$zipFile->addFile($file, $entryName);

// you can specify a compression method
$zipFile->addFile($file, $entryName, \PhpZip\Constants\ZipCompressionMethod::STORED); // No compression
$zipFile->addFile($file, $entryName, \PhpZip\Constants\ZipCompressionMethod::DEFLATED); // Deflate compression
$zipFile->addFile($file, $entryName, \PhpZip\Constants\ZipCompressionMethod::BZIP2); // BZIP2 compression
ZipFile::addSplFile

Adds a \SplFileInfo to a ZIP archive.

// $file = '...../file.ext'; 
// $entryName = 'file2.ext'
$zipFile = new \PhpZip\ZipFile();

$splFile = new \SplFileInfo('README.md');

$zipFile->addSplFile($splFile);
$zipFile->addSplFile($splFile, $entryName);
// or
$zipFile[$entryName] = new \SplFileInfo($file);

// set compression method
$zipFile->addSplFile($splFile, $entryName, $options = [
    \PhpZip\Constants\ZipOptions::COMPRESSION_METHOD => \PhpZip\Constants\ZipCompressionMethod::DEFLATED,
]);

    ->name('*.{jpg,jpeg,gif,png}')
    ->name('/^[0-9a-f]\./')
    ->contains('/lorem\s+ipsum$/i')
    ->in('path');

$zipFile = new \PhpZip\ZipFile();
$zipFile->addFromFinder($finder, $options = [
