What are the recommended methods for testing and debugging PHP scripts that involve dynamic code execution?

When testing and debugging PHP scripts that involve dynamic code execution, it is recommended to use tools like Xdebug for step-by-step debugging, logging functions to track the flow of dynamic code, and writing unit tests to ensure the expected behavior of the dynamic code.

// Example PHP code snippet using Xdebug for debugging dynamic code execution

// Enable Xdebug for step-by-step debugging
xdebug_start_trace();

// Your dynamic code execution here

// Stop Xdebug tracing
xdebug_stop_trace();
