Module 4: The Debugging Masterclass (The "Independence" Module)

  • Xdebug Proficiency: Mandatory session. Conditional breakpoints, stack traces, and variable watching.
  • Profiling Tools: Using Blackfire/XHProf to identify "why is this page slow?"
  • Log Analysis: Reading dblog and server logs to reconstruct a crash.
  • The "Break It" Lab: I will intentionally break the site. You must use Xdebug to find the line of code and fix it live.
