infinite recovery

Php returns the code for the list of infinitely classified data with arrays. Copy the code as follows: * ---------------- *-obtain the list data of an infinite category *------------------ The code is as follows: /*------------------*///-Obtain the list data of an unlimited category/*------------------*/Function get_sort ($ parent_id = 0, $ n =-1){Global $ db;Static $ sort_list = array ();$ SQL = "SELECT * FROM". $ db-> table ('article _ sort '). "

This article mainly introduces two examples of infinite classification methods in php. This article provides examples of infinite classification implemented by recursive and non-recursive methods. For more information, see 1. recursive methods The code is as follows: $ Items = array (Array ('id' => 1, 'pid '=> 0, 'name' => 'Level 1 11 '),Array ('id' => 2, 'pid '=> 0, 'name' => 'Level 1 12 '),Array ('id' =>

There are many infinite classification methods on the internet. to create a shopping website, we need many sub-classes. I don't know which one is the best? Unlimited classification which is the best? Rt; please help us to introduce it. recursion is definitely not needed. I still have an infinite array classification method and nested set model. that's good. I will post a tutorial by the way. thank you!

the str according to the project requirements to generate an unlimited rating list: Include_once ('connect. php'); // connect to the database. write an echo get_str (0) in the connect. php file. // output an infinite classification. The effect is as follows: Next, let's look at the functions that return the array format, and use recursion as well: Function get_array ($ id = 0) {$ SQL = "select id, title from class where pid = $ id"; $ result = my

Graphic set 5: incorrect use of HashMap causes infinite loops and element loss, correct hashmap Problem cause The previous article explains the implementation principle of HashMap and explains that HashMap is NOT thread-safe. So What problems does HashMap have in a multi-threaded environment? A few months ago, when a module of the company's project was running online, there was an endless loop, and the code of the endless loop was stuck on the HashM

Use CSS to implement the indentation with the background infinite nesting, support Ie6, the code is as follows:　　CSS implementation indentation infinite nesting

With a For loop and a while loop, you can read any number from the keyboard, input 0 automatically jumps out of the infinite loop, and determines that there are several negative numbers.Infinite loops for 1.for loops:1 ImportJava.util.Scanner;//referencing the scanner class for reading keyboard input2 classTestxunhuan3 {4 Public Static voidMain (string[] args)5 {6 inta=0;//record number of positive numbers7 intb=0;//record num

Realize infinite Pole column classification idea: Get the self-increment ID (that is, the parent ID) and then get the child ID (that is, the UID sub-ID) data to the database as followsId:1 uid:0 I am the column 1Id:2 uid:1 I am the column 2Id:3 Uid:1 I'm a subclass of column 1 Show Results:I am the column 1I'm a subclass of column 1.I am the column 2 $query = $this->db->query ("Select * from category");$list = $query->result ();foreach ($list as $v)

This article provides a detailed analysis of the implementation algorithm of php's left and right value infinite classification. For more information, see This article provides a detailed analysis of the implementation algorithm of php's left and right value infinite classification. For more information, see I. IntroductionIn terms of product classification, Hong Kong servers, multi-level tree-struct

We know that many open source software's infinite classification is the recursive algorithm, but we know that recursion is a waste of time, but also a waste of space (memory), Last time I also shared a my own original infinite classification spanning tree method, a enthusiastic php expert netizens gave me a valuable advice, I tested it, this code of time very short reference: http://www.oschina.net/code/sni

First, preface A simple description, the practice of a few principles, thinking, actually write a lot of things, thought is the most important. 1, Target: Will write an infinite node tree directory structure, such as Steps: 1, your download plugin ztree. And then decorate it in your project. 2. Related CSS The above CSS and JS to your own prevail. 3. Directory Structure div 4, the code of their own separate JS The relevant functions and configur

$result [] = $row;//assigns the array to $result getList ($row [' id '], $result, $SPAC);//Recursive Call, Call yourself this argument in parentheses and above getlist ($pid =0 ...) is the same as $row[' id ']== $pid =0; } return $result;//Returns the result} $rs = GetList ();//Use Method Var_dump ($RS);//Print method result The above infinite classification uses the recursive algorithm, the recursive algorithm simple explanation

What this article brings to you is about how PHP implements infinite pole classification. (with code), there is a certain reference value, the need for friends can refer to, I hope to help you. In the writing of the project to use the infinite pole classification, because of the special reasons for the project, the menu bar needs to call the method multiple times, with static variables to save the array wh

This article mainly introduces the method of PHP infinite pole classification, the interested friend's reference, hope to be helpful to everybody. The code is as follows: If it's with smarty,Add one more The code is as follows: $smarty->assign (' Wuxian_class ', $AA); Add this sentence to the HTML page. Another issue to note is that $STR must be global, otherwise there will be an error. Extension of infinite
