TinyButStrong is a template class for PHP that allows you to generate XML/HTML pages and any other files based on text source. The engine gives facilities to work with any databases, including in native PDO, MySQL, PostgreSQL, SQLite, PHP arrays, and more. It is possible to design templates using any visual editor (like Dreamweaver or FrontPage), and thus to make templates that are compatible with W3C standards for example. It features simple block management, useful display formats, conditional displaying for blocks and locators, remote XML/HTML attribute modification, a cache system, and the ability to include sub-templates and execute associated scripts. Plug-ins are supported since version 3.0.
PDO4You is a class that implements the Singleton design pattern for connecting the database using the PDO extension (PHP Data Objects). It provides an abstraction layer for accessing data, regardless of which database you are using, and ensures that there is a single object instance per database connection. It can connect to several possible SQL databases using the available PDO drivers. Currently it supports MySQL, PostgreSQL, SQLite, MariaDB, Oracle, Microsoft SQL server, Sybase, and CUBRID (a database highly optimized for Web applications). The class can also execute multiple queries at once given a string in JSON format that specifies the type of query, the tables, fields, field values, conditions, etc.
