X7Chat是一个开源聊天室系统。具有不限制房间数，用户数，完全可管理控制，多种消息样式等特点。许多开源项目多已经把X7Chat集成到其项目中使用如：Mambo4.5.X，PhpBB2.0.X，PhpNuke7.X，PostNuke0.075，Xoops等。
X7 Chat 3 is a complete recode of X7 Chat designed primarily with efficiency and stability in mind. The first alpha release has already been made available on the forums and development is currently proceeding at a rapid pace. X7 Chat 3 will support almost all of the features of X7 Chat 2 in addition to many new and updated features. The code will also be much cleaner thanks to the introduction of a better object oriented coding system and customization of the layout far easier thanks to a new template system.
If you wish to put in any feature requests for Version 3 now is the best time to do so; we have established a version 3 feature request board on our forums for submitting feature requests for Version 3 (registration is not required).
The X7 Chat project has joined the Go PHP 5 project and starting with X7 Chat 3 only PHP 5.2 and newer will be supported. If your webhost does not support PHP 5 now is the time to start requesting it. PHP 5 will allow X7 Chat 3 to support many advanced features while consuming far fewer server resources.
