Phar, The PHP .exe Format
The document discusses PHP Archives (Phar), which allow packaging of multiple PHP files into a single file. Phar is built into PHP and provides advantages like single file downloads, easy upgrades, and security against modifications. Key aspects of Phar include the stub, manifest, file contents, and optional signature. Phar can be used to distribute full applications, libraries, plugins and more via a single file.
