bloginfo()

The database. More specifically, the [prefix]options table, where [prefix] is the table prefix you specified during installation (defaults to wp_).

Thanks!

What is the difference between bloginfo() and get_options?

live627,

The Codex is your friend:

https://codex.www.ads-software.com/Function_Reference/get_option

If you want a short answer, bloginfo() has access to about 20 settings, while get_option() allows you to retrieve all options that are defined. A list of those options is available here:

Additionally, bloginfo() outputs the values, while get_option() returns them for programmatic use. There is also get_bloginfo() that works just like bloginfo(), except it returns values like get_option() does.
