XML User Profiles is a system that allows for remote and transferable user accounts. The file format is a lightweight but flexible vCard transformation that allows better profile sharing and simpler implementations than FOAF. The current specification and a few sample implementations in PHP are provided. The library currently allows for authentication against the simple LOGIN interface or the Drupal XML-RPC service in addition to the distributed and strong authentication LID-1.0 and OpenID-0.0 single-sign-on systems.
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.
gCache is a PHP class that can be used to capture and cache Web page content. It can store cached content in files of a given directory. It uses OS independent file locking to prevent corruption from simultaneous attempts to update the cache files. First, it checks whether the cache file exists and has not expired. In that case, it retrieves the cache content into a class variable. If the cache does not exist or has expired, the class can start capturing the output of the current script. When the script is done, the class can store the captured content in the cache file.
PHP gFeed is a PHP class that implements a stream wrapper to read and write RSS feeds. It can be used to parse RSS feeds with path specified in the URL and stores the parsed feed values in global variables. It can also generate RSS feeds from values from the same global variables.
gHttp is a class that implements an HTTP stream wrapper that can be used to access Web pages like files. It can submit HTTP POST and GET requests using regular PHP access functions with support for authentication and using proxy servers. It provides the stream wrappers ghttp, phttp, ghttps, and phttps for performing HTTP GET and POST requests respectively using SSL or not. They can also be used as replacements for the regular HTTP stream wrappers under PHP 5.1 or later. Optionally, it can cache the responses of the same HTTP requests in files of a given directory.
The PHP DOM Template system is a fast PHP template engine that is aimed at maximizing development between designers and developers. It attempts to put a clean divider between the two teams. This template system can work in a Dreamweaver environment, which is often ideal for designers.
