PHP & WordPress : print array content

Question

我现在很笨……

print_r($terms);

这是……

Array
(
    [7] => stdClass Object
        (
            [term_id] => 7
            [name] => Testwhatever
            [slug] => testwhatever
            [term_group] => 0
            [term_taxonomy_id] => 7
            [taxonomy] => event_type
            [description] => 
            [parent] => 0
            [count] => 2
            [object_id] => 8
        )

)

如何打印 slug？ 我认为 print print($terms->slug) 应该可以完成这项工作，但它说:“尝试获取非对象的属性”

更新:

function get_event_term($post) {
    $terms = get_the_terms( (int) $post->ID, 'event_type' );
    if ( !empty( $terms ) ) {
        print_r($terms);
        return $terms[7]->slug;
    }
}

Answer 1

它是一个对象数组(即使它只包含索引“7”处的单个条目)，而不是单个对象

echo $terms[7]->slug;

有多个“事物”

foreach ($terms as $term) echo $term->slug;
