PHP WebDAV extension project allows easy access to remote resources with PHP through the DAV protocol.
Installation
This extension requires the Neon library and the related header files.
Neon can be downloaded from: http://www.webdav.org/neon/
Pre-built packages and ports are already available for most operating systems and distributions.
In order to compile and install the PHP WebDAV extension, just follow the standard PECL procedure :
$ phpize
$ ./configure --enable-dav
# make install
On OpenBSD systems, use
$ env AUTOCONF_VERSION=2.61 phpize
(replace 2.61 with any of the currently installed versions of autoconf on your system)
Basic example
webdav_connect(http://webdav.example.com/dav, davuser, davpassword);
$a = webdav_get(/my/nice/object.txt);
webdav_put(/your/nice/thing.txt, $data);
webdav_unlink(/unwanted_resource.txt);
webdav_rename(/dir/old_name, /dir/new_name);
webdav_copy(/dir/orig_dir, /dir/new_dir, TRUE);
webdav_close();
Named resource example
$res = webdav_connect(http://webdav.example.com/dav, davuser, davpassword);
$a = webdav_get(/my/nice/object.txt, $res);
webdav_put(/your/nice/thing.txt, $data, $res);
webdav_unlink(/unwanted_resource.txt, $res);
webdav_rename(/dir/old_name, /dir/new_name, $res);
webdav_copy(/dir/orig_dir, /dir/new_dir, TRUE, $res);
webdav_close($res);
Enhancements:
- This release fixes a bug in webdav_put() and introduces a wrapper to access DAV resources through PHP streams.

ffmpeg-php is an extension for PHP that adds an easy to use object-oriented API for retrieving information from movies and audio files.
It has methods for returning frames from movie files as images that can be manipulated using PHPs image functions.
This works well for automatically creating thumbnail images from movie files. ffmpeg-php is also useful for reporting the duration and bitrate of audio files (mp3, wma...). ffmpeg-php can access many of the formats supported by ffmpeg.
Main features:
- Simple object oriented interface.
- Has methods to grab frames from movie files and return them as images that can be manipulated using PHPs built-in image functions. This is great for automatically creating thumbnails for movie files.
- Has the ability to use ffmpegs excellent resampling and cropping features on returned images.
- Provides access to data from mp3 files such as duration, bitrate and track meta information.

Ruby Chess is a chess game implemented in Ruby using GTK2. Ruby Chess project has a good artificial intelligence that is heuristic-based and stochastic.

This extension library provides the filesystem primitives to your Lua scripts, which are missing from the core language. The exported primitives include mkdir, rmdir, stat, chown, chmod, and more.
Available filesystem primitives:
chdir()
chmod()
chown()
cwd()
is_dir()
is_file()
mkdir()
readdir()
rmdir()
stat()
This project was started when I was coding a simple Lua webserver and became frustrated at the lack of available filesystem primitives.
Enhancements:
- This is the first stable release of the software with complete documentation and a sufficiently useful set of exported primitives.
