How to delete a folder (containing the files in it) in php

php traverses all files and folders in a folder, and deletes the code of all files under all folders and subfolders, achieving the effect of emptying a directory through recursion .

Function used:

scandir($path) Traverse all files in a folder and return an array.
unlink($filename) Delete the file.
rmdir($path) Delete only empty folders

<?php
 //设置需要删除的文件夹
  $path = "./Application/Runtime/";
  //清空文件夹函数和清空文件夹后删除空文件夹函数的处理
  function deldir($path){
   //如果是目录则继续
   if(is_dir($path)){
    //扫描一个文件夹内的所有文件夹和文件并返回数组
   $p = scandir($path);
   foreach($p as $val){
    //排除目录中的.和..
    if($val !="." && $val !=".."){
     //如果是目录则递归子目录，继续操作
     if(is_dir($path.$val)){
      //子目录中操作删除文件夹和文件
      deldir($path.$val.&#39;/&#39;);
      //目录清空后删除空文件夹
      @rmdir($path.$val.&#39;/&#39;);
     }else{
      //如果是文件直接删除
      unlink($path.$val);
     }
    }
   }
  }
  }
 //调用函数，传入路径
 deldir($path);
