Article Introduction：Xdebug is the core tool of PHP debugging, and can achieve breakpoint debugging with IDE; lightweight tools such as var_dump(), error_log() and Laravel's dd() are suitable for simple troubleshooting. The installation method varies according to the system: Linux uses pecl or package manager, macOS uses brew, and Windows enables dll files. Key configurations include enabling error reporting, setting log paths, IDE port synchronization, and using browser plug-ins to assist debugging. Ignoring these details may cause debugging failures.

Article Introduction：Common methods and tools for front-end debugging include: 1. Use browser developer tools to troubleshoot basic problems, including viewing and modifying DOM structure, debugging JavaScript code, and viewing network request details; 2. Use console output and logs to track problems, such as using different levels of logs, grouping output, formatting output; 3. Use debugger breakpoints to deeply analyze, support single-step execution, entry of functions, and jumping out of functions; 4. Use special debugging auxiliary tools, such as ReactDeveloperTools, VueDevtools, Lighthouse, and ReduxDevTools. Mastering these techniques can effectively improve debugging efficiency and code quality.

Article Introduction：The methods of debugging Python code mainly include: 1. Use pdb for command line debugging; 2. Use the graphical debugging function of the IDE; 3. Record logs through the logging module; 4. Use third-party debugging tools. pdb is a debugger built into Python. You can insert pdb.set_trace() into the code or start it through the command line to perform single-step execution, view variables, etc.; IDEs such as PyCharm and VSCode provide graphical interface debugging functions such as breakpoints and monitoring expressions, which are suitable for complex logic problems; the logging module can replace print output, support multi-level control and diversified output targets, which are convenient for log management at different stages; ipdb, Py-Spy, c

Article Introduction：There are many options for Python debugging tools, suitable for different scenarios. 1. The command line debugger pdb is a standard debugging library built into Python, suitable for basic debugging needs. It can be enabled by inserting code using importpdb or breakpoint(), and supports breakpoints, single-step execution and other operations; 2. The IDE's own debuggers such as PyCharm and VSCode provide graphical interfaces, which support clicking to set breakpoints, view variables, conditional breakpoints and other functions, which are more suitable for use when developing complex projects; 3. Third-party debugging tools include ipdb (combined with IPython to enhance interactive experience), pudb (terminal visual debugging) and py-spy (performance analysis). They need to be installed first to optimize different debugging needs.

Article Introduction：The key to debugging HTML application browser developer tools is to master several core functions. 1. Use the "check" function to view the DOM structure to confirm whether the elements exist and whether the tags are nested correctly; 2. Edit HTML and CSS in real time, test the modification effect and check style conflicts; 3. Use the box model panel to check layout parameters such as margin, border, padding; 4. Set breakpoints or listen for DOM changes to track the dynamic modification of JavaScript. Proficient in using these methods can efficiently locate and solve common problems in HTML debugging.

Article Introduction：Xdebug: Powerful debugging and performance analysis tools for PHP developers Core points: Xdebug is a powerful, free and open source PHP extension that provides debugging support, stack trace, performance analysis, code coverage and other functions. It allows developers to pause the execution of the application at any time and check the value of variables to better understand how PHP is running. Xdebug can be used as a performance analysis tool for PHP applications, recording important details such as statements and functions execution time and number of calls. Analyzing these outputs allows you to understand where the bottleneck lies, thereby optimizing your application for performance. To use Xdebug, it needs to be installed and configured correctly. XAMPP or MAMP is pre-installed with XDEbug.

Article Introduction：Troubleshooting PHP code problems with temporary annotations is an efficient way, especially when debugging tools are lacking. 1. Reduce the scope of the problem by commenting large segments of logic, and gradually relax the observation of behavior changes; 2. Comment the subsequent interfering code, focus on testing variable values, and avoid being affected by redundant logic; 3. Use comments instead to delete function calls, retain structure and test process changes, such as the replacement conditions are judged as fixed values; 4. Pay attention to avoid dependency errors caused by nesting multi-layer comments and be careful about annotation database operations, and manage changes with the help of version control tools. Mastering these techniques can significantly improve debugging efficiency.

Article Introduction：When debugging PHP code, the rational use of annotation control debug information can avoid interfering with the output and exposing sensitive data. 1. Use single-line comments to temporarily block debugging code, such as //echo'variable value'; to facilitate quick activation in the future; 2. Use if(false) condition to determine more flexible switching control to improve debugging efficiency; 3. Be careful not to submit comment debugging code to the production environment, avoid syntax errors caused by nested comments, and use IDE shortcut keys to improve operation efficiency. These methods can effectively optimize the debugging process and reduce the risk of errors.
