Why is get_the_category() saying that I have two categories?

by

My post has only one category. The following code:

$categories = get_the_category();

gives me this result:

Array
(
    [0] => stdClass Object
        (
            [term_id] => 22
            [name] => Style Guide
            [slug] => style-guide
            [term_group] => 0
            [term_taxonomy_id] => 22
            [taxonomy] => category
            Why is get_the_category() saying that I have two categories? => 
            [parent] => 0
            [count] => 2
            [object_id] => 391
            [cat_ID] => 22
            [category_count] => 2
            [category_description] => 
            [cat_name] => Style Guide
            [category_nicename] => style-guide
            [category_parent] => 0
        )

)

Why is it double up?

I’m guessing you’re referring to the 

[category_count] => 2

when you say “saying that I have two categories”?

If so, you should understand that category_count is not the number of cateogries that this post has, but rather it is ‘the number of uses of this category (also stored as ‘count’)’ – see get_the_category function reference. The fact that there is only one array element in the returned object indicates that there is only 1 category assigned to this post.

count($categories)

… will give you what you are looking for.
