One of the great things of mysqlnd as a base library for PHP's MySQL support are the collected statistics. mysqlnd collects about 160 different statistical values about all the things going on. When having such an amount of raw data it, obviously, is quite hard to draw conclusions out of it. Therefore I recently created a PHP library sitting on top of this feature to collect all data, run some analysis and then provide some guidance and made it available from the JSMysqlndAnalytics GitHub repo (see there also for instructions for using Composer).

Using the library is relatively simple as the short instructions show. The library consists of two main parts. On the one side the "Collector"  this is a wrapper around …

Previously I was writing about combining Symfony2 and mysqlnd to get more statistics on what is going on below the surface in the database communication when using a Symfony2 application via the Symfony2 profiler.
