In this new post to his blog Gonzalo Ayuso has shared a simple SQL wrapper that he uses to work with his databases. It takes in an injection of the database connection component (a href="http://php.net/pdo">PDO) and provides functionality for inserts, updates, etc. with transaction support.
If we don't use an ORM within our projects we need to write SQL statements by hand. I don't mind to write SQL. It's simple and descriptive but sometimes we like to use helpers to avoid write the same code again and again. Today we are going to create a simple library to help use to write simple SQL queries.
It's a lightweight library that'd be good for basic uses, but when you start getting into something a bit more complex, something like Doctrine2 or Propel might be a better solution (or whatever your framework of choice has built in).
