If you want to use the "mysqli" extension, you've come to the right place. This is the second part of the series “Using mysqli with PHP 5.” Welcome back. In three tutorials, this series shows how to use the most important methods and properties included in the “mysqli” extension that comes with PHP 5, in order to take advantage of the new features bundled with MySQL 4.1 and above.

Introduction

Stepping back for a moment to the topics that I covered in the first tutorial, you’ll probably remember how to connect to the MySQL server and use the “multi_query()” method for running multiple queries, in addition to handling several result sets at the same time. This can definitely can introduce significant changes to the way that you develop your MySQL-based applications.

Also, I’d like to mention the great functionality provided by this extension to bind different queries to specific parameters, which are replaced with real values during the execution of an application. This particular feature allows the definition of “generic” queries that eventually will be attached to different arguments, resulting in an easier and more flexible process for generating dynamic queries.

All right, I believe that all the topics I mentioned before are now fresh in your mind. Therefore it’s time to move on and focus our attention on the subject of this second article, so you know what to expect from it. Over the course of this installment, I’ll explain how to use the “commit()” and “rollback()” methods included within the “mysqli” library, among other handy methods, which hopefully will provide you with a more robust grounding in the capabilities of MySQL 4.1 and above.

Are you ready to continue learning more about all these useful features? Okay, let’s get started!
