Network Tagline
Using this example, you can obtain the name and description for the network home:
results in this being displayed on your blog:
The Network Home URL is: http://example.com/
The Network Home Name is: Example
The Network Home Tagline is: The example site
There should be a possibility to return the array of all available info. Although this might not be a good practice in terms of performance this should help someone who needs to fetch all info about a website. Note that I’ve omitted some fields that might not be that important:

$blog_title.Blog Tagline
Using this example:
Results in this being displayed on your blog:
Your Blog Tagline is: All things WordPress
Blog Title
This example assign your blog’s title to the variable
$blog_title. This returns the same result as the default usage.The comments regarding `get_bloginfo(‘url’)` are misleading. It will *not* necessarily return what is set in Settings > General. The protocol (“http” or “https”) will be determined by the value of `is_ssl() `, which detects if the current request is over SSL or not.
