•  site_url() — Site URL for the current site (for example, http://php999.blogspot.com)
•  home_url() — Home URL for the current site (for example, http://php999.blogspot.com)

Confused by seeing site_url and home_url?

Here is the explanation. Site_url() will give your exact blog address and home_url() will give you the domain address.

Consider this example, we have hosted our wordpress blog in http://php999.blogspot.com/blog/index.php

Site_url returns => http://php999.blogspot.com/blog
Home_url returns => http://php999.blogspot.com
