PHK is a library and application packager. It is a
sort of PHP-oriented jar. As such, it allows you
to distribute and run a whole application as a
single file. It includes many features and
options, such as on-the-fly decompression, Web
access restriction, CRC consistency checks,
digital signatures, meta-packages, an integrated
autoloader, etc. PHK also provides a standard way
to display every information about the package,
like its documentation and license, through an
embedded mini-website called webinfo mode.
