How does XDebug compare to using microtime for measuring script execution time in PHP?

XDebug is a powerful debugging and profiling tool for PHP that provides detailed information about script execution, including profiling data like function call times and memory usage. Using XDebug for measuring script execution time is more accurate and comprehensive than using microtime, as it provides detailed insights into the performance of the script. To use XDebug for profiling, you need to install the XDebug extension and configure it in your PHP settings.

// Enable XDebug profiling
xdebug_start_profiling();

// Your PHP script code here

// Stop XDebug profiling
xdebug_stop_profiling();

// Output the profiling data
echo xdebug_dump_function_profile();
