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. ### <a name="Documentation"></a> Documentation: #### <a name="Documentation-Overview"></a> Overview of methods of the class `\PhpZip\ZipFile` - [ZipFile::__construct](#Documentation-ZipFile-__construct) - initializes the ZIP archive. - [ZipFile::addAll](#Documentation-ZipFile-addAll) - adds all entries from an array. - [ZipFile::addDir](#Documentation-ZipFile-addDir) - adds files to the archive from the directory on the specified path without subdirectories. - [ZipFile::addDirRecursive](#Documentation-ZipFile-addDirRecursive) - adds files to the archive from the directory on the specified path with subdirectories. - [ZipFile::addEmptyDir](#Documentation-ZipFile-addEmptyDir) - add a new directory. - [ZipFile::addFile](#Documentation-ZipFile-addFile) - adds a file to a ZIP archive from the given path. - [ZipFile::addSplFile](#Documentation-ZipFile-addSplFile) - adds a `\SplFileInfo` to a ZIP archive. - [ZipFile::addFromFinder](#Documentation-ZipFile-addFromFinder) - adds files from the `Symfony\Component\Finder\Finder` to a ZIP archive. - [ZipFile::addFilesFromIterator](#Documentation-ZipFile-addFilesFromIterator) - adds files from the iterator of directories. - [ZipFile::addFilesFromGlob](#Documentation-ZipFile-addFilesFromGlob) - adds files from a directory by glob pattern without subdirectories. - [ZipFile::addFilesFromGlobRecursive](#Documentation-ZipFile-addFilesFromGlobRecursive) - adds files from a directory by glob pattern with subdirectories. - [ZipFile::addFilesFromRegex](#Documentation-ZipFile-addFilesFromRegex) - adds files from a directory by PCRE pattern without subdirectories. - [ZipFile::addFilesFromRegexRecursive](#Documentation-ZipFile-addFilesFromRegexRecursive) - adds files from a directory by PCRE pattern with subdirectories. - [ZipFile::addFromStream](#Documentation-ZipFile-addFromStream) - adds a entry from the stream to the ZIP archive. - [ZipFile::addFromString](#Documentation-ZipFile-addFromString) - adds a file to a ZIP archive using its contents. - [ZipFile::close](#Documentation-ZipFile-close) - close the archive. - [ZipFile::count](#Documentation-ZipFile-count) - returns the number of entries in the archive. - [ZipFile::deleteFromName](#Documentation-ZipFile-deleteFromName) - deletes an entry in the archive using its name.
