问get_the_category() wordpress函数在更新核心版本后停止工作

EN

//get category 

$category   = get_the_category(get_the_ID());

//the above code will return an Array

Array
(
    [0] => WP_Term Object
        (
            [term_id] => 2
            [name] => video
            [slug] => video
            [term_group] => 0
            [term_taxonomy_id] => 2
            [taxonomy] => category
            [description] => 
            [parent] => 0
            [count] => 1
            [filter] => raw
            [cat_ID] => 2
            [category_count] => 1
            [category_description] => 
            [cat_name] => video
            [category_nicename] => video
            [category_parent] => 0
        )

)

// you can access this array like this

$catID = $category[0]->term_id;
//for term id

$catName = $category[0]->name;
//for category name
