get_category( int|object $category, string $output = OBJECT, string $filter = 'raw' )

Retrieves category data given a category ID or category object.

Description Description

If you pass the $category parameter an object, which is assumed to be the category row object retrieved the database. It will cache the category data.

If you pass $category an integer of the category ID, then that category will be retrieved from the database, if it isn’t already cached, and pass it back.

If you look at get_term(), then both types will be passed through several filters and finally sanitized based on the $filter parameter value.

The category will converted to maintain backward compatibility.

    Example passing Category ID (integer):

    <?php $category = get_category( 106 ); ?>

    The output of print_r( $category ); would be similar to:

    stdClass Object
    [term_id] => 106
    [name] => Category Name
    [slug] => category-name
    [term_group] => 0
    [term_taxonomy_id] => 108
    [taxonomy] => category
    [description] => This is the category description.
    [parent] => 62
    [count] => 17
    [filter] => raw
    [cat_ID] => 106
    [category_count] => 17
    [category_description] => This is the category description.
    [cat_name] => Category Name
    [category_nicename] => category-name
    [category_parent] => 62
