# The PharData class

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

## Introduction

The PharData class provides a high-level interface to accessing and creating non-executable tar and zip archives. Because these archives do not contain a stub and cannot be executed by the phar extension, it is possible to create and manipulate regular zip and tar files using the PharData class even if `phar.readonly` php.ini setting is `1`.
