Introduction

The Stanford Web Application Toolkit (SWAT) is a set of tools designed to assist Stanford web developers in creating secure and robust PHP-based web applications. It gives the programmer straightforward methods for connecting to the database, searching the directory, authorization, sending e-mail, handling file uploads (coming soon), defending against SPAM (coming soon), and other common-but-often-tedious tasks. SWAT has three primary goals: security, accessibility, and ease of use. The toolkit is broken down into several modules.
