5. Debugging Tips

Use var_dump() or print_r() to output the file handle and function return values to observe the program state.
Enable error display to catch potential warnings and errors.
Ensure the file exists and has the correct read permissions.
Use stream_get_meta_data() to check the file stream metadata and troubleshoot anomalies.

Summary

Although rewind() is a simple and easy-to-use function, to achieve safe and reliable file pointer resets, it must be combined with proper error handling and debugging techniques. By checking resource validity, using fallback solutions, and enabling error reporting, you can significantly improve code robustness and maintainability.
