php实现无限级评论功能

CREATE TABLE comment ( comm_id INT UNSIGNED PRIMARY KEY AUTO_INCREMENT, user_id INT UNSIGNED NOT NULL DEFAULT 0 , parent_id INT UNSIGNED NOT NULL DEFAULT 0 , article_id INT UNSIGNED NOT NULL DEFAULT 0 , comm_cont TEXT, comm_time INT UNSIGNED NOT NULL DEFAULT 0 ) ENGINE=MYISAM CHARSET=UTF8 ;

function get_childs_comment($comments, $parent_id = 0, $level = 0) { $new_comments = []; foreach ($comments as $key => $val) { if ($val['pid'] == $parent_id) { $val['level'] = $level; $val['childs'] = get_childs_comment($comments, $val['id'], $level + 1); $new_comments[] = $val; } } return $new_comments; }

[ '一级评论', 'childs' => [ '二级评论' 'childs' => [ '....' ] ] ]
