How can xdebug be utilized to profile PHP code and analyze performance issues in a website?

To profile PHP code and analyze performance issues in a website using xdebug, you can enable the profiler in your php.ini file and set xdebug.profiler_enable=1. Then, trigger the profiler by adding XDEBUG_PROFILE=1 to the URL of the page you want to profile. Finally, analyze the generated cachegrind file using a tool like KCachegrind or WinCacheGrind to identify performance bottlenecks. 

// Enable xdebug profiler in php.ini
xdebug.profiler_enable=1;

// Trigger the profiler by adding XDEBUG_PROFILE=1 to the URL
// Example: http://example.com/page.php?XDEBUG_PROFILE=1

// Analyze the cachegrind file using KCachegrind or WinCacheGrind
