great talk on a good tool
Making Your Life Easier: Xdebug
Derick Rethans (Oct 10, 2009)
Talk at PHP North West 2009 (English - UK)
This session teaches you how to detect and debug PHP scripts with the free open source tool Xdebug, which is an extension to PHP. The first part will quickly show how to get started with Xdebug. The second part of the session will cover detecting problems in your scripts by showing how Xdebug provides debugging aides in the form of stack/function traces, dumps of variables, modified PHP functions. In the last part I will show the remote debugger capabilities of Xdebug, where you can: set breakpoints on functions, methods and file/line combinations; watch execution details such as stack frames, per-frame information; run PHP code to modify the current state of your script and evaluating error messages. On top of this you will also see how you can use Xdebug’s profiler to find bottlenecks in your applications.

I have had xdebug installed for some time now, solely for profiling. I wasn't aware of tracing before now and will be using it asap!

Thanks for the presentation, xdebug is really useful tool. Can I recommend a new config feature - ability to turn on/off level of extended stack trace per type of PHP error (notice/warning/fatal/etc ...). It would help to keep server logs size at reasonable level. Thanks in advance !

Very good talk. I'd never heard of xdebug but I'll definitely give it a go!

Interactive remote debugging was a real eye opener. I thought stuff like this was limited to desktop app development! Great presentation, and live demos are always great to see at tech conferences :)

Having not looked into Xdebug before this presentation was actually a real eye opener for me, I will definitely be trying this out even if it's just on my own development server at home.

Exactly what it said on the tin - always a pleasure to listen to Derick's voice, the informed content and "active" delivery come as a bonus!

Technically full on, but very useful.

A really good talk that introduced me to exactly what Xdebug can do which is great because it looks like a really helpful tool. Good demos and presentation.

An excellent talk that showcased some features that I didn't know were in XDebug. It wasn't too technical either so there was no brain-fatigue afterwards.
Derick is an excellent speaker and kept me interested throughout.

Derick mentioned KCacheGrind as a Linux application for viewing xdebug's profiling output. As KDE4 runs also on Windows it is possible to run KCacheGrind on this platform as well.

Excellent. Lots of new options/ features (to me) well worth attending.
