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.
asql allows you to run SQL queries against log files formatted in the Apache common log file format. You may load multiple log files into a session, then run queries using a full SQL implementation, to find things such as the most common referers to your site, the greediest downloaders, and much more. Internally, each log file is parsed and imported into a temporary SQLite database, so performance is very good.
