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

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

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

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

Each one Unlimited ClassificationYou need to record its parent ID, when it is a top-level taxonomy, the parent ID is 0. This way no matter which classification can be identified by the parent ID layer of the parent, so that it is clear to know what

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

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: ". $n. $class _arr[$i][1]. " \n "; }else{$str. = "". $n. $class _arr[$i][

This article mainly introduces the creation of PHP Infinite-level Tree menu, the main use of recursive functions, interested in the small friends can refer to Write recursive functions, you can consider caching, define some static variables to save

First on Top class classification is actually a first-class classification, two-level classification is also called sub-classification classification, on this basis, sub-classification can also have sub-classification, which constitutes an
