Working with ZIP Archives
PHP zip functions create ZIPs with ZipArchive.
Introduction to ZipArchive
PHP's ZipArchive class provides a convenient and powerful way to create, modify, and manage ZIP compressed files. This class is part of the PHP standard library and offers a wide range of methods to handle ZIP files efficiently.
Creating a New ZIP Archive
To create a new ZIP archive, you need to instantiate the ZipArchive class and use the open() method with the appropriate flags. The ZipArchive::CREATE flag is used to create a new archive if it does not exist.
Adding Files to a ZIP Archive
Once you have a ZIP archive open, you can add files using methods like addFile() and addFromString(). The addFile() method is used to add existing files, while addFromString() creates a new file from a string.
Extracting Files from a ZIP Archive
You can extract files from a ZIP archive using the extractTo() method. This method extracts all files to a specified directory.
Closing a ZIP Archive
After performing all operations on a ZIP archive, it is important to close the archive using the close() method. This ensures that all changes are saved and the file is not corrupted.
