The bloginfo() WordPress PHP function displays various pieces of information about the current site. It’s a handy tool for retrieving key site details, such as the site name, URL, and description.
Usage
Here’s a simple usage of the function:
bloginfo('name'); // Outputs the site name
Parameters
- $show (string, optional) – Specifies the site information to display. Default is an empty string.

See WordPress Developer Resources: bloginfo()
The function echoes the result immediately, so if you need to use any of the bloginfo() parameters as variables, you should use get_bloginfo() instead. This function returns the result as a string.
Examples
Display the Blog Title
To display the title of your blog, you can use the following code:
<h1>bloginfo('name');</h1> // Displays your blog's title in a h1 tag.
Display the Blog Description
Here’s how to display the tagline of your blog as set in Settings > General:
<p>bloginfo('description');</p> // Displays the tagline of your blog in a p tag.
Show the Blog Title in a Link
This example displays the blog’s title in a link:
<a href="bloginfo('url');" title="bloginfo('name');">bloginfo('name');</a>
Hide Description if Empty
This practical example could be used as it is in themes. It hides the description if it’s empty:
if (get_bloginfo('description') !== '') {
echo '<a class="site-description">bloginfo('description');</a>';
}
Show the Character Set
To display the character set your blog is using (e.g., “utf-8”):
<p>Character set: bloginfo('charset');</p>
