Easy Debugger is a simple class that makes debugging complex sites very simple. The class allows you to clearly and easily output strings, variables, and objects and color code them for easier reading. It also makes it incredibly simple to output strings, variables, or even objects to email for simple troubleshooting or AJAX pages and pages where reload doesn't allow debugging. It saves debug output until the end of the page; groups all outputs from a page together; groups all outputs from specific files together; has easy color coding for advanced troubleshooting; shows line numbers and file names so you don't lose debug items; and has simple helper functions to speed up use. Debugs can be left on while the site is live, with no unwanted interruption. This code has been used on over 100 sites, from simple HTML pages to complex Web applications.

The ApPHP TreeMenu is a PHP script that generates a multi-level tree menu control. It was specially designed for Web developers. A tree menu is one of the most popular and commonly used navigation controls, and this script allows you to set one up and use it in no time. It has a collapsible vertical tree listing that resembles the Windows Explorer folder view. It also makes it easier for visitors to find things, looks professional, and helps to organize a large amount of data into a hierarchical order with as many nodes and sub-levels as you need. Expandable elements can be used as links or just expanded. The sub-menus are opened and closed by a mouse click.
