Debugging is one of the most important and significant parts of software development. Finding bugs and errors in any application is a tedious task, so a proper debugging mechanism should be adopted to make the process easier. Without following proper debugging procedures, software bugs and errors can be difficult to locate. As per the PHP programming model, we should be aware of all the tools available for debugging and eliminating malfunctioning components from our software system. In this article, we will concentrate on the core PHP debugging process. The core mechanism consists of using the program to trace errors and discrepancies. The output is gathered through the script execution and displayed at the end of the script.



Normally when we work on software development process, we have to follow Software Development Life Cycle (SDLC) guidelines. The SDLC process consists of different types of steps and one of them is the debugging and testing process. Debugging is an essential part of any software development work.

When we develop a software project, it invariably contains different types of bugs, errors or abnormalities. Debugging is the process of checking, detecting and correcting errors or bugs to allow software programs to function properly.


General Trouble Shooting Strategies

Basic elements of a debugging effort consist of guessing the problem and then fixing it. It does not matter whether we are analyzing an PHP program, a telephone switch, an electronics circuit, or a software program -- certain principles apply, regardless. So we should bear these ideas in mind as we try to figure out what ails our software.



The following assumes that you are familiar with the concept of unit testing, as well as the PHP web development language. It is a guide for a new user with the Simple Test process. If you are new to the unit testing process then it will also help you follow the steps.
