Summary ✨

The code outputs a HTML string that displays various information about the current PHP script execution, including:
The URI string
Controller and function called
Memory usage
Benchmarks (e.g., query time)
GET and POST request data
Query logs
This output is likely used for debugging or profiling purposes.
