HomePHP Page 2 - User Authentication with patUser (part 1)
Power User - PHP
Need to add authentication to your PHP-based Web application? Getit done in a jiffy with patUser, a PHP class which makes it possible torapidly add powerful user management capabilities to your Web application.
There are a number of reasons why you might want to add user authentication to your Web site. You might want to restrict access to certain pages only to a specific group of privileged users. You might want to customize the content on your site as per user preferences. Or you might just want to track user movement between the pages of your site. Regardless of why you want to add it, you should know how to go about doing it reliably and efficiently.
patUser, in the author's words, is a "user management class, that helps you with authentication, group and permission management, statistics and more". Developed by Stephan Schmidt, it is freely available for download and is packaged as a single PHP class that can be easily included in your application.
Very simply, patUser provides application developers with a set of APIs that ease the task of managing and authenticating users within the framework of a Web application. It includes a number of well-thought-out functions designed to manage users, organize users into groups, assign privileges to users and groups, and track user logins for audit purposes. The model on which patUser based is simple enough that it can be quickly understood and exploited for rapid deployment, yet flexible enought that it can be easily extended to build fairly sophisticated user management systems for Web applications.
If you're in the business of building Web applications, and if those applications are designed to support multiple users with different privileges, you're going to find patUser invaluable to your development cycle. Written as a PHP class, patUser can easily be integrated into any PHP-based Web application, and can substantially reduce the amount of time you spend on designing, building and deploying multi-user applications. You'll find it functional, powerful and (if you're the kind who likes fiddling) easily extensible, and it'll soon be a standard component of every application you write.
Before proceeding further, you should visit the patUser home page at http://www.php-tools.de/ and download a copy of the latest version (2.1 at the time of writing). The package contains the main class file, documentation outlining the exposed methods and variables, and some example scripts.
