![]() This returns valid php, if variable exists, else returns false. And this is faster comparatively to print_r() This prints along with type, length of each value. To check the value of some variable, print_r(), var_dump(), var_export(). There wouldn’t be any developer who hasn’t used this! Let me talk about a few techniques that I have used for debugging PHP.Ī simple and most common way to check if the function or the method you have written is being called up, write an exit. So, you can solve the bugs if you have knowledge on multiple methods of php debugging. All you need is some setup to add the key to your code base and you are all set to analyse any functionality using the documentation. By using this, I found the function that is eating up the checkout process. This gives you a more user-readable option of the stack trace of all the functions, the time taken for each function in the whole process. The tool that helped me in php debugging and solving this case is Blackfire. So I started with checking off the options from the list one by one such as, (a) Is it because of some plugin? (b) Is it Theme related? (c) Is it any custom code base? etc. In this case, I don’t have much knowledge on how things work with Wordpress. There is a commerce site built on Wordpress in which the checkout process was taking around 5-8 minutes and I was asked to solve it. Okay so here is a case that I have come across in my development career. Debugging is an art that can get better with practice and experience. Where do we start from? We start by analyzing the code step by step to understand what is done and where things are going wrong. Picture this - The codebase is big, You are new to the project, You do not have much details of the project/functionality. ![]() This depends on their experience, their problem-solving approach and most importantly - the amount of time they have in hand! How important is debugging and why do you need to debug your code?ĭebugging is an integral part of a software development life cycle that assures quality results. Every PHP developer has a different style and go-to methods for debugging their code. Developers detest bugs but to be able to build a fine quality software, debugging is an indispensable part of a developer’s life. Debugging is not something us developers look forward to. ![]()
