wp_count_posts( string $type = 'post', string $perm = '' ): stdClass
Counts number of posts of a post type and if user has permissions to view.
Contents
Description
This function provides an efficient method of finding the amount of post’s type a blog has. Another method is to count the amount of items in get_posts() , but that method has a lot of overhead with doing so. Therefore, when developing for 2.5+, use this function instead.
The $perm parameter checks for ‘readable’ value and if the user can read private posts, it will display that for the user that is signed in.
Parameters
-
$type
string Optional -
Post type to retrieve count. Default
'post'
.Default:
'post'
-
$perm
string Optional -
'readable'
or empty.Default:
''
Return
stdClass Number of posts for each status.

Get the Publish Status Post Count
To get the published status type, you would call the wp_count_posts() function and then access the ‘publish’ property.
If you are developing for PHP5 only, then you can use shorthand, if you only want to get one status. This will not work in PHP4 and if you want to maintain backwards compatibility, then you must use the above code.
This function returns an object whose properties you can access:
So, to find out if you have more than 1 post published try:
Basic Example
The default usage returns a count of the posts that are published. This will be an object, you can var_dump() the contents to debug the output.

Feedback
This comment is a bit misleading. The first sentence is incorrect. Without wp_debug set to true we do not receive the warning that it, as the rest of the comment states, returns an object, not “a count of the posts that are published”. — By Mike Ritter —
Count Drafts
Counting drafts is handled the same way as the publish status.
Count Pages
Counting pages status types are done in the same way as posts and make use of the first parameter. Finding the number of posts for the post status is done the same way as for posts.
Other Uses
The wp_count_posts() can be used to find the number for post statuses of any post type. This includes attachments or any post type added in the future, either by a plugin or part of the WordPress Core.
