The debugging process has historically been a challenging and time-consuming one for scripting as well as programming language, which is why many developers would resort to using hacks. Funnily enough, many of these hacks would not work as expected, meaning developers would often end up going back and forth the output and PHP code.
PHP debugging techniques are much easier these days, with a number of PHP debugging tools and PHP frameworks available for developers across all skillsets.
Why Use Debugging Tools?
Users must know how to fix any problems expected to occur while coding with debug tools and PHP extensions. Once the bug is fixed, the software will be ready for deployment and use. Debugger tools can identify code errors at different stages, from compile-time to runtime. With these, developers can execute the program step-by-step by evaluating the value of variables, and stop the execution wherever required.
The Top 6 PHP Debugging Tools Available for Your Use:
Kint
Kint is a debugging tool that outputs information about variables and traces. The debugging process is presented in a styled, collapsible format that is easy to understand and handle. The Kint Debugger coordinates with the Debug Bar plugin through a panel that displays your debug results for your convenience. It is easy to use as compared to other debugging tools, as it works on install and run libraries. Kint also offers remote debugging.
Features
- Displays the variable name and file + line where Kint was called from.
- Detects and formats CLI automatically.
- Easy and fast to dump variables.
Pros
- The user can disable all output easily so they can easily debug on the live environment.
- Kint shows you every piece of the physically available information regarding what you are dumping.
- The Kint Debugger integrates seamlessly with the Debug Bar plugin.
Cons
- The source code sent does not automatically sync with the one within the editor. With every release, it can prove
- troublesome to match up.
- Requires good connection to the remote server every time you have to access the code live project
