user_info is a class to retrieve information about the browser the user is using to access the current site script. It can analyze the user agent string sent by the browser in the current HTTP request and extracts the type of browser, user machine operating system, user machine IP address, accepted character set encoding, language name, and whether the user is a spider/bot.
Simple Login Class is a PHP class that can be used to prevent unauthorized access of Web pages. A simple user management system can be implemented with this class very quickly. It does not use databases or database queries to store the user details. Instead of a database, it uses a text file to store the details. An access encoding technique (Base64), two hashing techniques (SHA1 and MD5), an a built-in PHP function (StrRev) are used here to store passwords more securely in the text file. Simple Login Class can be used in any PHP page just by embedding a snippet at the top of a the page to be protected. Any number of user logins can be stored more securely in a single file. The sessions are handled more safely in this system than some other login systems. The user registration system applied here is simplified. In certain cases, no configuration is needed to use this class.
php mudnames is a PHP class that can generate random names for characters used in role playing games such as multi-user dungeon (MUD) games. Although the names do not mean anything, they sound very much like typical names of characters that you often see in this kind of game. It can retrieve text data from one of several dictionary files. The dictionary data is used to generate random names based on selected capabilities and used particles.
MidCOM, the Midgard Components Framework, is an MVC framework for the Midgard persistent storage platform. It provides mechanisms for building a Web site using components without much need for writing code to glue all this together. The administration site gets built automatically by using those components. Goodies like a caching engine and sub-requests make site building even easier.
RSS Writer Class is a PHP class that can generate RSS (Rich/RDF Site Summary) XML documents. It extends the XML Writer class to generate XML-RSS documents. It features simplified definitions of channel and item properties, support for defining optional channel graphic images and search form text inputs, support for RSS specification versions 0.9, 0.91, 1.0, and 2.0, support for using namespace modules to extend the document property set, and an optional XSL stylesheet example to automatically view RSS documents as HTML pages in XML capable browsers.
polygon is a set of PHP classes that can be used to perform different types of geometric operations with arbitary polygons. It provides generic polygon and vertex classes that support mixing lines and arc segments between vertices. Polygons may be self-intersecting, convex, or concave. It provides means to perform intersection and union operations with the shapes and to compute shape clipping.
phpass is a portable password hashing framework for use in PHP applications. The preferred (most secure) hashing method supported by phpass is the OpenBSD-style bcrypt (known in PHP as CRYPT_BLOWFISH), with a fallback to BSDI-style extended DES-based hashes (known in PHP as CRYPT_EXT_DES), and a last resort fallback to an MD5-based variable iteration count password hashing method implemented in phpass itself.
