PI calculator collection 3.0 Hamish Milne -- 2431 2007-07-09 02:02:13 [ show ]
The php pi() function can only go to a certain amount. This is a collection of Pi calculators using the Gregory-Leibniz series, the Wallis series and the Reimann series, in float and BCMath. The float is faster but can only go to a certain number of decimal places. Tested on 5.2.3 but should work on 4+. BCMath functions require BCMath support, Windows PHP 4.0.4 plus should be fine. See php.net/bc for details. Warning: I have had problems using pi_wallis_bc and pi_reimann_bc. The code is right so there seems to be a bug in the BCMath functions.
ApPHP TreeMenu 1.0.1 Chara Miteo -- 1305 2010-04-11 03:52:38 [ link ] [ show ]
The ApPHP TreeMenu is a PHP script that generates multilevel tree menu control. It was specially designed for web developers. Tree menu is one of the most popular and commonly used navigation controls and it allows you to set up and use in no time. It has a collapsible vertical tree listing, that resembles the Windows Explorer folder view. It also makes it easier for visitors of your website to find things, makes its look more professional and helps to organize large amount of data into hierarchical order with as many nodes and sub-levels as you need. Expandable elements can be used as links, or they can be just expanded. The sub-menus are opened and closed by a mouse click.
