DbSimple is a database abstraction library which provides an extremely laconic and handy interface for practical usage in PHP 4/5 scripts. Its usage is much easier than most of other popular abstraction libraries (like ADODB, PEAR DB, and PDO). "Query execution" and "result fetching" operations are joined thogether and complemented by powerful placeholder support (including list-based placeholders) and various fetching modes. The library supports a unique and very convenient method to build dynamic SQL queries (conditional macro-blocks).
