PHP two methods and techniques for implementing stepless recursive classification

This article mainly introduces two methods for implementing stepless recursive classification in PHP, which has good reference value. Next, let's take a look at the small series. This article mainly introduces two methods for implementing stepless recursive classification in PHP, which has good reference value. Let's take a look at it with the small editor.

For more information, see the code:

/*** Stepless recursive classification TP framework * @ param int $ assortPid parent id of the category to be queried * @ param mixed $ delimiter between the upper and lower levels of the tag * @ return string $ tree returned classification tree structure result **/function recursiveAssort ($ assortPid, $ tag = '') {$ assort = M ('goods _ class')-> where (" class_pid = $ assortPid ")-> field ('class _ id, class_name ')-> select (); foreach ($ assort as $ value) {$ tree. =''. $ Tag. $ value ['class _ name'].''; $ Tree. = recursiveAssort ($ value ['class _ id'], $ tag. 'category');} return $ tree ;}

/*** Use php reference to pass the CI framework **/public function get_access () {$ access = array (); $ field = 'id, pid, method, name, description '; $ q_access = $ this-> db-> select ($ field)-> get ('access'); $ q_result = $ q_access-> result_array (); if (! Empty ($ q_result) {$ items = array (); foreach ($ q_result as $ value) {$ items [$ value ['id'] = $ value ;} foreach ($ items as $ key => $ item) {if ($ item ['pid '] = 0) {$ access [] = & $ items [$ key];} else {$ items [$ item ['pid '] ['sub _ access'] [] = & $ items [$ key] ;}} return $ access ;}

The above are two methods and techniques for implementing stepless recursive classification in PHP. For more information, see PHP Chinese website (www.php1.cn )!
