In this new post to his site Rob Allen shows you how to implement a simple logging method for catching exceptions in your Zend Framework 2 application.
I recently had a problem with a ZF2 based website where users were reporting seeing the error page displayed, but I couldn't reproduce in testing. To find this problem I decided to log every exception to a file so I could then go back and work out what was happening. In a standard ZF2 application, the easiest way to do this is to add a listener to the 'dispatch.error' event and log using ZendLog.
He uses an event listener to attach a service that contains a "logException" method. This method uses the ZendLog component to write out the error message to a local log file including a backtrace of where the issue occurred.
