Zendcon2009 ended this past week, and we introduced a new beta version of Zend Server 5.0 with several new features. In this article and video blog I will review Code Tracer. Think of it as a blackbox flight recorder for your PHP applications. When something goes wrong with an airplane, everything is saved during the flight onto the blackbox to help the investigators figure out what went wrong. What if you can do that in production with your PHP applications to figure out problems when they happen, now you can with the new Zend Server 5.0 Code Tracer.
In this video I will setup Zend Server Tracer to capture a problem from an open source application called phpExcelReader . There are two problems with this project once you download it from sourceforge that Zend Server can help you quickly identify it and fix it. I wanted to keep this first example real simple to show how to setup the CODE TRACE and used a real world FOSS application with the typical white screen problem that is so common with development. There are far more difficult problems that this feature can help you solve, including performance issues, code problems and even segfault issues when they happen a trace is the only thing that can help you figure it out. Let me know what problems this feature has helped you identify in your project, drop me a post here.
