Moodle event observers “fire” asynchronously based on events that get triggered by user activity, and so… hard to catch and debug by simply passing the XDEBUG variable via the browser.
Enters… xdebug_break()

jokkedk/webgrind: Xdebug Profiling Web Frontend in PHP
Webgrind is a Xdebug profiling web frontend in PHP. It implements a subset of the features of kcachegrind and installs in seconds and works on all platforms. For quick’n’dirty optimizations it does the job. Here’s a screenshot showing the output from profiling:
Features
- Super simple, cross platform installation – obviously 🙂
- Track time spent in functions by self cost or inclusive cost. Inclusive cost is time inside function + calls to other functions.
- See if time is spent in internal or user functions.
- See where any function was called from and which functions it calls.
- Generate a call graph using gprof2dot.py
Suggestions for improvements and new features are more than welcome – this is just a start.
