thinkPHP实现递归循环栏目并按照树形结构无限极输出的方法_php实例
本文实例讲述了thinkPHP实现递归循环栏目并按照树形结构无限极输出的方法。分享给大家供大家参考,具体如下:
这里使用thinkphp递归循环栏目按照树形结构无限极输出,并保存为一个数组,利于模板调用
具体代码如下:
private function categoryTree($parentid,$level) //因为是本类中使用所以定于为私有函数 { $Category= D('Category'); $result = $Category->where("`parentid`=".$parentid)->order("listorder desc,catid desc")->select(); if($result) { $count=count($result);//当前子栏目个数 $level++;//子栏目层级 foreach($result as $v) { $index++; if($count==$index) $step="└─"; else $step="├─"; $step.=str_repeat(' ',$level-1); $nbsp=str_repeat(' ',$level-1); $nstr=$nbsp.$step; if($parentid==0) $nstr=''; $v['step']=$nstr; $newData[$v['catid']]=$v; //echo $nstr.$v['catname']."<br />"; if($v['child']==1)//如果有子栏目 { $newData=$newData+$this->categoryTree($v['catid'],$level); } } } return $newData; }
php递归栏目保存为数组

"Development Suggestions: How to Use the ThinkPHP Framework to Implement Asynchronous Tasks" With the rapid development of Internet technology, Web applications have increasingly higher requirements for handling a large number of concurrent requests and complex business logic. In order to improve system performance and user experience, developers often consider using asynchronous tasks to perform some time-consuming operations, such as sending emails, processing file uploads, generating reports, etc. In the field of PHP, the ThinkPHP framework, as a popular development framework, provides some convenient ways to implement asynchronous tasks.

ThinkPHP is a high-performance PHP framework with advantages such as caching mechanism, code optimization, parallel processing and database optimization. Official performance tests show that it can handle more than 10,000 requests per second and is widely used in large-scale websites and enterprise systems such as JD.com and Ctrip in actual applications.

Development suggestions: Overview of how to perform logging in ThinkPHP applications: Logging is a very important task when developing web applications. It can help us monitor the running status of the application in real time, locate problems and solve bugs. This article will introduce how to perform logging in ThinkPHP applications, including log classification, storage location and configuration method. At the same time, some logging best practices will also be shared. 1. ThinkPHP’s log classification: ThinkPHP supports multiple types of log classification
