Chapter 5. Debugging and Profiling

During development, every developer faces problems, and it becomes unclear what is really going on here and why the problem is generated. Most the time, these issues can be logical or with the data. It is always hard to find such issues. Debugging is a process to find such issues and problems and fix them. Similarly, we often need to know how many resources a script consumes, including memory consumption, CPU, and how much time it takes to execute.

In this chapter, we will cover the following topics:

  • Xdebug

  • Debugging with Sublime Text 3

  • Debugging with Eclipse

  • Profiling with Xdebug

  • PHP DebugBar
