Meunity is a Web-based community system that uses PHP. It is object oriented, so it is easily extendible. Its database abstraction layer allows it to be compatible with multiple databases. It is easily configurable, and includes content management systems and advanced administration.
User Manage is a compact suite which can easily be used in any PHP script. It is modeled like a puzzle: there is the "core" that handles basic authentication, and then there are other modules that handle utility functions (e.g. a database handler that helps top-level modules like the permissions handler). With User Manage, developers can build applications with the standard user authentication complete, and developers can drop in modules to handle extra user information and to add functionality.
phpMyBackend is a backend generator for MySQL databases. After defining the fields that are browsable, sortable, and searchable and turning image uploads on or off, it produces a fully functional backend that allows users to add, delete, modify, search, and sort records, and view image thumbnails.
class_sql_inject is a PHP class that searches your SQL data values for special characters that may change the meaning of your SQL data and execute actions that may compromise the security of servers. When some of these suspicious character sequences is found in HTTP POST request values ($_POST), you can either destroy the current session, redirect to a new page, or log the activity.
