PHP Shell is a shell wrapped in a PHP script. It's a tool you can use to execute arbiritary shell-commands or browse the filesystem on your remote Web server. This replaces, to a degree, a normal telnet-connection. You can use it for administration and maintenance of your Web site using commands like ps, free, du, df, and more.
Multi-router looking glass for PHP is a full rewrite of the Perl version of MRLG into PHP. It allows network administrators to execute commands on multiple routers via a nice Web interface. It is flexible, clear, and configurable. Default, per-router, and per-service options may be set. The Web-page layout and queries set are adjustable.
Webtunnel is a network utility that encapsulates arbitrary data in HTTP and transmits it through a Web server. In that regard, it is similar to httptunnel. However, its server component runs in the context of a Web server as a CGI application (with optional FastCGI support), so it does not need its own port. It supports most things that the Web server supports, such as authentication, HTTP 1.1, HTTPS, and client certificates. It uses simple requests and responses so it works seamlessly through forward and reverse proxies.
suPHP is a combination of an Apache module (mod_suphp) and an executable which provides a wrapper for PHP. With both together, it is possible to execute PHP scripts with the permissions of their owner without having to place a PHP binary in each user's cgi-bin directory. suPHP doesn't need Apache's suExec, and provides a logging function.
The Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.). It employs tag cleaning and paging so that Web pages it can access have far greater chances of being rendered on devices that cannot display overly large or complex pages. It is simple, but it seems to substantially extend the portion of the Web available from devices that otherwise display messages like "413: Page cannot be displayed."
Gravacacher is very simple and lightweight caching server designed for one specific purpose: to cache avatar images from services like www.gravatar.com, which provide "globally recognized avatars". Typically, Gravacacher will be deployed on sites that host blogs or forums which depend on gravatars. Gravacacher supports a security mechanism that allows it to answer only queries made via URLs generated by your server software, such as blog or forum engines, permanent cached entities, and both positive and negative TTLs when caching.
phpBBHC (PHP Big Brother Hosts Configurator) is a collection of PHP scripts and one C program to give a Web-based interface for adding, deleting, and modifying hosts which are monitored by Big Brother. Although Big Brother has since been replaced by Hobbit, phpBBHC can still configure Hobbit thanks to the backwards compatibility of Hobbit.
