infinite looper

This article summarizes the two PHP Unlimited class implementation program code, there is a need to learn friends can refer to. Main idea: First look at the third row and the fourth row, the parent class ID (parentid) value is 1, representing the subclass belonging to the Id=1 class, whereas, one, 22 rows because it is a first class classification, there is no superior classification, so the parent class ID (parentid) value is 0, represents the primary classification, An

-comment as a sub-array of the parent comment, but as I write this can not be nested multi-layered comments, infinite pole nesting to do so?Thank you for asking for help! Solution: Is it possible to understand the problem of infinite classification? Infinite class Classification $list = Array (' ID ' =>1, ' fid ' =>0, ' title ' = ' China '), array (' ID ' =>2, '

Function: Infinite classification shows function get_str ($id = 0) { global $str; $sql = "Select Classid,classname,classstate,classtype,classurl,classpage,classorder,classtitle,classkeyword, Classdescription,classpid from Bz_class where classpid= $id "; $result = mysql_query ($sql);//The subclass of the query PID if ($result mysql_affected_rows ()) {//If there is a subclass while ($row = Mysql_fetch_array ($result)) {//cycl

PHP Create infinite-level tree menu, PHP Create-tree Write recursive functions, you can consider caching, define some static variables to save the results of the last run, multi-program run efficiency is very helpful.The approximate steps are as follows :Step1: take data to a database, put it into an array,Step2: Converts the data into a tree-shaped array,step3: convert this tree-shaped array to HTML code.You can also combine the second and third ste

Always want to do the effect of circular slide slide, similar to PPTV, such as the home page effect is very sorry, not the whole GIF motion diagram ~ ~ ~Less nonsense, first look at the effect:The idea is: Set Pageradapter count as Integer.max_value, but the actual item only a few, with the way to take the remainder of the item, set the adapter at the same time set the CurrentItem to the actual item number n times ( Be big enough). This allows you to slide seamlessly around the loop! (After all,

Use CSS3 's animation animation properties to achieve 360° infinite loop rotation.Code snippet://Picture path customizationCSS styles are written as follows:#change {position:absolute; right:200px;-webkit-animation:change 2s linear infinite;}@-webkit-keyframes Change{0%{-webkit-transform:rotate (0deg);}50%{-webkit-transform:rotate (180deg);}100%{-webkit-transform:rotate (360deg);}}Get!!!

Python multi-dimensional/nested Dictionary data infinite traversal implementation, python multi-dimensional Recently I picked up Django and learned how to traverse multi-dimensional Dictionary data in the instance practice. Google does not query related information... After all, I was a newbie. When I started my work, I found that it was not just as simple as I thought. I had two twists and turns to achieve the effect. I recorded the process and hoped

If a function calls itself directly or indirectly, it forms a recursive (recursion), such as an implementation of the Fibonacci sequence.def fib (n): if n : return 1 else: return fib (n-1) + FIB (n-2)Recursion must have an end condition, otherwise a dead loop is formed, such as the following example:def A (): B ()def B (): if__name__'__main__ ' : A ()An exception will be thrown soon:runtimeerror:maximum recursion depth exceededWhat will be reported this anomaly, ve

When you learn PHP unlimited pole classification, we all feel a word "difficult" I also find it difficult, so, now are still watching, because the work to use, so, it must be studied.To the Internet a search PHP infinite classification, a lot, but a lot of is a, and, write very messy, code a lot, let us how to learn, those are not reliable, or self-ramming drum unlimited pole classification.For example, a category table: with ID, name, PID, sort on th

PHP infinite loop to obtain MySQL Data instance code, mysql instance Recently, the company has a need to obtain data from MySQL, and then display the data on the page in a loop. It is mainly to keep clicking a button, and then the data starts from the beginning to the end. If the data at the end is not enough, then add several records from the beginning of the data. In fact, this function can be implemented through JQ or through PHP + MYSQL, but JQ is

Implementation example of JQuery asynchronous loading of the infinite drop-down box cascade Function This article mainly introduces the implementation of JQuery asynchronous loading of the infinite drop-down box cascade function. For more information, see The Code is as follows: JQuery asynchronously loads the infinite pole drop-down box cascade Function Zjy */

Infinite pole classification, how to add classified products Infinite pole classification, how to add classified products, in addition to recursive call classification, because a lot of classification ------Solution-------------------- Want this infinite pole of thing, have bound data source! Design a good data structure is good! ------Solution-----------------

If a function calls itself directly or indirectly, it forms a recursive (recursion), such as an implementation of the Fibonacci sequence.def fib (n): if n Recursion must have an end condition, otherwise a dead loop is formed, such as the following example:Def a (): B () def b (): A () if __name__ = = ' __main__ ': A ()An exception will be thrown soon:runtimeerror:maximum recursion depth exceededWhat will be reported this anomaly, very simple, we all know that the subroutine call need

A simple explanation　　One problem with the previous program is that it cannot be looped, because there are only five arrays in the plist file, so the first and last ones are gone, and here are some tips for dealing with this kind of loop presentation problem.　　Method One: Use a For loop, loop 200 times, create a 200*=1000 model, and the default program starts in the 100th group position, there are 500 models forward, there are 500 backward models, creating a loop to show the illusion.The code is
