Categories are an important part of a website, and WordPress offers a lot of features regarding categories. Typically, categories are saved with two mandatory options, one is the id and the other is their name.

When we deal with categories and need to use them on our website, we need an ID from which we can call a specific category or use that ID to get information about a specific category.

WordPress provides the following methods to get all the information about a category.

get_the_cateGory( $id )

The above method will return all categories of the current post or page or categories for a given post ID. This method will return an array that will contain the following objects.
