PHP and Flutter are popular technologies for mobile development. Flutter excels in cross-platform capabilities, performance and user interface, and is suitable for applications that require high performance, cross-platform and customized UI. PHP is suitable for server-side applications with lower performance and not cross-platform.

C++ multi-thread debugging can use GDB: 1. Enable debugging information compilation; 2. Set breakpoints; 3. Use infothreads to view threads; 4. Use thread to switch threads; 5. Use next, stepi, and locals to debug. Actual case debugging deadlock: 1. Use threadapplyallbt to print the stack; 2. Check the thread status; 3. Single-step the main thread; 4. Use condition variables to coordinate access to solve the deadlock.

How to use LeakSanitizer to debug C++ memory leaks? Install LeakSanitizer. Enable LeakSanitizer via compile flag. Run the application and analyze the LeakSanitizer report. Identify memory allocation types and allocation locations. Fix memory leaks and ensure all dynamically allocated memory is released.

This article introduces shortcuts for Go function debugging and analysis, including: built-in debugger dlv, which is used to pause execution, check variables, and set breakpoints. Logging, use the log package to record messages and view them during debugging. The performance analysis tool pprof generates call graphs and analyzes performance, and uses gotoolpprof to analyze data. Practical case: Analyze memory leaks through pprof and generate a call graph to display the functions that cause leaks.

Concurrency testing and debugging Concurrency testing and debugging in Java concurrent programming are crucial and the following techniques are available: Concurrency testing: Unit testing: Isolate and test a single concurrent task. Integration testing: testing the interaction between multiple concurrent tasks. Load testing: Evaluate an application's performance and scalability under heavy load. Concurrency Debugging: Breakpoints: Pause thread execution and inspect variables or execute code. Logging: Record thread events and status. Stack trace: Identify the source of the exception. Visualization tools: Monitor thread activity and resource usage.

Tools for debugging PHP asynchronous code include: Psalm: a static analysis tool that can find potential errors. ParallelLint: A tool that inspects asynchronous code and provides recommendations. Xdebug: An extension for debugging PHP applications by enabling a session and stepping through the code. Other tips include using logging, assertions, running code locally, and writing unit tests.

Common PHP debugging errors include: Syntax errors: Check the code syntax to make sure there are no errors. Undefined variable: Before using a variable, make sure it is initialized and assigned a value. Missing semicolons: Add semicolons to all code blocks. Function is undefined: Check that the function name is spelled correctly and make sure the correct file or PHP extension is loaded.

C++ debugging functions that contain exception handling uses exception point breakpoints to identify exception locations. Use the catch command in gdb to print exception information and stack traces. Use the exception logger to capture and analyze exceptions, including messages, stack traces, and variable values.
