ThinkPHP清除缓存/删除文件夹下所有文件

今天做了一个ThinkPHP清除缓存功能,在网上开了一下有一个比较简单的写法但是那个是ThinkPHP内置的一个类,我找了半天没找到这个类,气死我了  于是就用php删除文件夹下所有文件这个方法来达到清除缓缓存的的功能,废话不多说粘上代码:

/*此方法为公共方法用来删除某个文件夹下的所有文件
     * $path为文件的路径
     * $fileName文件夹名称
     * */
    public function rmFile($path,$fileName){
        //去除空格
        $path = preg_replace('/(\/){2,}|{\\\}{1,}/','/',$path);    
        //得到完整目录    
        $path.= $fileName;
        //判断此文件是否为一个文件目录
        if(is_dir($path)){
            //打开文件
            if ($dh = opendir($path)){
                //遍历文件目录名称
                   while (($file = readdir($dh)) != false){
                       //逐一进行删除
                       unlink($path.'\\'.$file);
                       }
                       //关闭文件
                      closedir($dh);
                }    
            }
    }

//一对一删除缓存
    public function cache(){

        //前台用ajax get方式进行提交的,这里是先判断一下
        if($_GET['type']){

             //获取提交过来的值(也就是要删除的文件夹名称)

            $type=$_GET['type'];

            //获取文件的绝对路径

            $abs_dir=dirname(dirname(dirname(dirname(__FILE__))));

            //与要删除的文件夹里的文件进行组合
            $pa=$abs_dir.'\Admin\Runtime\\';

           //调用上面写好的方法

            $this->rmFile($pa,$type);

            //返回提示信息
            $this->ajaxReturn(1,'清除成功',1);
        }else{
            $this->display();
        }
    }

//一键清除所有缓存
    public function allrun(){

        ////前台用ajax get方式进行提交的,这里是先判断一下
        if($_GET['type']){

          //得到传递过来的值
            $type=$_GET['type'];

            //将传递过来的值进行切割,我是已“-”进行切割的
            $name=explode('-', $type);

            //得到切割的条数,便于下面循环

            $count=count($name);

           //循环调用上面的方法

            for ($i=0;$i

                //得到文件的绝对路径

                $abs_dir=dirname(dirname(dirname(dirname(__FILE__))));

                //组合路径
                $pa=$abs_dir.'\Admin\Runtime\\';

                //调用删除文件夹下所有文件的方法
                $this->rmFile($pa,$name[$i]);    
            }

           //给出提示信息

            $this->ajaxReturn(1,'清除成功',1);
        }else{
            $this->display();
        }
    }

前台页面很简单 在这里就给出重要的代码

html文件

//这个是ajax get方式提交




                     

                      

                           //关键就是这个隐藏域的默认值 就是你要删除文件夹里面内容的文件夹的名

                           
                       
                       
                     
                     

                

//一键清除所有


                     
                      

                            //默认值是几个文件夹的名字连起来 提交方式和上面的一样

How does garbage collection work for PHP sessions?How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How can you trace session activity in PHP?How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
