超快查询所有子孙
画个table，写了样式，居然被替换的面目全非，所以，干脆做成HTML算了。
查询子集
SELECT * FROM `table` WHERE `pid` = 3
查询子孙集
SELECT * FROM `table` WHERE `place` LIKE '%/3/%'
查询某代子集
SELECT * FROM `table` WHERE `place` LIKE '%/3/%' AND `level` = 4
插入
$insert_id = INSERT INTO `table` (`name`,`pid`) VALUES('面试专员','10')
$parent = SELECT * FROM `table` WHERE `id` = 10
UPDATE `table` SET `place` = '{$parent['place']}{$insert_id}/',`level`= {$parent['level']} + 1 WHERE `id` = {$insert_id}
修改父级
$parent = SELECT * FROM `table` WHERE `id` = {$pid}
UPDATE `table` SET `pid` = {$pid},`place` = '{$parent['place']}{$insert_id}/',`level`= {$parent['level']} + 1 WHERE `id` = {$id}
