Confused in url's

[eluser]Sudz[/eluser]
When to use site_url() & base_url()?
What is the difference between site_url() and base_url()?
Can anybody help me?

Thanks in advance.

site_url() function is intended to used to reach your controller(because it will include your index file, in config.php,if you didnt leave it empty), while base_url() usually used for reached file or other stuff.
