    cde4php - Cross Database Engine for PHP

    Uniform Database Abstraction for PHP Development

    Debby has replaced CDE in the Tina4Stack, you may want to check it out at http://tina4.com CDE is a PHP class which implements the general database functions in PHP and provides a common SQL platform for php development where developers change their databases but not their code. Supports Firebird, MySQL,Oracle,SQLite, MSSQL(both drivers),CUBRID,ODBC. CDE now supports date uniformity, param passing & BLOB handling across all the databases supported. CDE is not a replacement for PDO, in fact we may implement PDO in CDE to standardize PDO results and calls. Some PDO drivers are still regarded as EXPERIMENTAL on PHP website, so use with caution. Feel free to suggest any features you wish to be added or submit a bug report with the tracker
