MQL is a PHP class that acts as a database access wrapper for using the MySQL or MySQLi extensions. It can establish connections to a MySQL server, execute INSERT queries given the table name and field value arrays, execute SELECT queries and return single values or arrays with results, and execute arbitrary queries and return the number of result rows, the number of affected rows, or the last inserted identifier.
DBPersister (database persistent library) is a PHP library which helps you simply and clearly use your database, taking advantage of powerful object oriented programming. You can use DBPersister to manage data from your database to your application. You can do all the boring operations (like loading a single record, saving a single record (insert, update, replace), and deleting a single record) without writing SQL code.
