Symfony 2 and mysqlnd

In a previous blog posting I was mentioning that I'm working on a small hobby PHP project. As I'm using this project to update myself to current frameworks I've decided to use Symfony 2. Symfony provides a nice feature, which is the Symfony Profilier, an extensive logging and reporting system for Symfony developers to understand what's going on. A part of it is the Doctrine query logger which lists all database queries executed by Doctrine and their execution time.

This is nice but when we're using mysqlnd in our PHP build we have more information available. "So why not use that information," I thought and built a new bundle for Symfony 2 doing exactly that. The JSMysqlndBundle will take all the 150 or so statistic values collected, so they can be seen in the profiler (click screenshot for a larger view).

As this is the initial value, a quick Sunday morning hack, it has not all features I can imagine. Things one could do include

• Provide information on caching decisions and behavior when mysqlnd_qc is used
• Provide replication-related decisions when the new mysqlnd replication and load balancing plugin is used
• Take David's mysqlnd_uh-based query logging ideas and provide more information on any executed query
• ....
