The following small make up will bring you a PHP recursive traversal of files in a specified folder implementation method. I think this is quite good. now I will share it with you and give you a reference. Let's take a look at the file and folder
Php uses recursive functions to accumulate numbers. Php uses recursive functions to accumulate numbers. This article describes how php uses recursive functions to accumulate numbers and involves php recursive operations, for more information about
A recursive function is a self-called function that calls itself directly or indirectly in the function body. However, you must set the self-called conditions. If the conditions are met, the function itself is called, if not, terminate the
This article describes in detail the information about hierarchical tree expansion of PHP recursion implementation. For more information, see the examples in this article, for your reference, the specific content is as follows:

Implementation
Although the recursive algorithm is not a high-performance algorithm, we use a lot of recursion, such as Directory Traversal or tree structure, it will be useful, let's take a look at the analysis and examples of recursive algorithms. Although the
In some complex systems, it is required to classify the information columns infinitely, in order to enhance the flexibility of the system. So how does PHP implement an infinite class classification? We use recursive algorithms in this article and
Question {code...} answers how to simplify the following code, because $ I ~ $ IN is uncertain. If other algorithms are better than {code...}, view the distribution. (ByCSDN) {code...} Question
There is an array consisting of 30 1 ~ 999 key value
current to-do List !--? php function make_list ($parent ) {Global $tasks; Echo '

$todo"; if (Isset ($tasks [$task _id])) {//If the current ID has
The infinite-level tree can be said to be a significant feature of the infinite-level column, and we'll look at two different ways to do it next.
I. Database design
CREATE TABLE ' bg_cate ' (' cate_id ' int () unsigned not NULL auto_increment, '
Php recursion achieves unlimited classification php formatted array
// The mysql PDO used by the database is the same as the whole idea.
$ Conn = mysql_connect ('localhost', 'root', '123 ');
If
This article mainly introduces the recursive traversal of PHP to achieve unlimited classification, interested in the friend's reference, I hope to help you.
Infinite class classification is a kind of classification skills, such as departmental

To delete an empty directory is simple ~ aRmDir () function can be done, but to delete a non-empty directory, you will not be able to quickly delete, you must first delete the
The essence of recursion is to return the result after zero vertices exist. If there is no zero point, an infinite loop will occur. Therefore, how to judge whether zero point is an important point for the successful use of recursion is provided
The first method:
